Re: Installing FreeSwitch & FusionPBX on a Plug PC or RouterI might be able to test it soon with a 800Mhz Freescale CPU based router. The router with OpenWRT was reported to deliver 24MB/s write speeds through a USB2.0 port to an EXT4 formatted USB3.0 thumb, which is more than adequate for HD calls recording. Some modern 2-core CPU routers feature several USB3.0 ports now. That's ideal for large file copy over LAN, while torrent download speeds usually max out on most consumer networks at 3MB/s, and recommended for best quality HD audio & video communication bandwidth with Google Handouts WebRTC is up to 2.5 Mbps = 0.3 MB/s as per Bandwidth Calculator » web.forret.com/tools/ban ··· dth.asp? . So there's solid CPU performance reserve for simultaneous work with other processes at recording calls to disk (of course without media transcoding and VPN workload). Also interesting to see how call encryption by PBX may affect a router & plug PC CPU load - any stats?  |

R U saying if I bought a USB3 memory stick, format it with an EXT4 FS, plug it into my Dockstar USB2 port, it should easily deliver 20+ MBps while its cousin (USB2 memory stick) won't even be able to deliver 5 MBps? |

Yes, of course, it greatly depends on USB Thumb controller and flash type, and also on the device's USB controller model. Theoretical USB2.0 max bandwidth is 60MB/s. I just did a quick test with FreeSwitch and other processes running - inserted my SP 32Gb USB3.0 EXT4 Flash drive into a USB2.0 Dockstar port and run these USB Benchmark Tests » wiki.openwrt.org/inbox/b ··· ark.usb:root@DockStar:~# hdparm -Tt /dev/sdb1
/dev/sdb1:
Timing cached reads: 322 MB in 2.01 seconds = 160.53 MB/sec
Timing buffered disk reads: 92 MB in 3.00 seconds = 30.62 MB/sec

Will do some more real life tests with coping large torrent files (continuous writes), very small multiple files, and audio streams usually flashed to disk periodically from cache, but standard test averages are already clear (see bonnie++ results interpretation » www.coker.com.au/bonnie+ ··· dme.html ): thumb reads ~30MB/s (CPU 12%), writes ~20MB/s (CPU 16%) cache reads ~160MB/s (CPU 65%), writes ~105MB/s (CPU 55%) so a good USB3.0 Thumb is approaching USB2.0 HDD internal copy speeds on Dockstar, while flashes to RAM are a lot faster anyway. Plenty of CPU juice is left for phone call switching while recording calls. :) It also means fast and cool Aria2 handled torrent downloads without high and lengthy CPU load & overheating to an attached USB3.0 thumb or HDD with max total download speed at 3MB/sec delivered by most cable subs (no more than 2 torrents in parallel is advisable for optimum performance at such cable speeds). Of course torrent bites will be dumped to disk periodically from cache depending on available and set in the torrent client download cache size.

@ zamarac,
I've tried installing fusionpbx and freeswitch a couple of times on my Pogo E02 without success. I followed install instructions on fusionpbx site but ran in to trouble more than once. Can you please give details of how you did it.
Thanks |

Pogo E02 is the same ARM5 device as Seagate Dockstar, just arcnumber may be different. Abundant install details are given in the Manual (Installing FreeSwitch & FusionPBX on a Plug PC DockStar running OpenWRT) linked in this thread's 1st post. Once you read and tried to follow the Manual, you're welcome to let us know what went wrong. There're many folks who can help you here. |

I see I didn't read carefully the first time. I tried on debian I am not familiar with openwrt and do not have the time to learn it now. I guess I'll try the instructions for debian again.
Thanks |

There are a lot more commonalities than differences btw various Linux distributions. If you follow the above Manual, installing OpenWRT amounts to coping one file and unpacking one archive onto a USB stick, so its not THAT much to learn. Bootloader is also the same - Jeff's Uboot. Even if you install Debian, there is hardly any fundamental difference in installing FreeSwitch and FusionPBX on Debian anyway - just use precompiled packages available for your distro. If errors occur during setup, look through the Manual - they might be similar, or ask here. |

I tested three types of USB to RJ45 adapters with MK802. R9700 based adapter can only give about 5 Mbps. AX88772B chipset based ones can usually deliver 60 Mbps. I tried gigabit adapters also, they didn't work for me even for ASIX based ones. Maybe they will work if there's right drivers. |

The seller of this USB 2.0 To RJ45 Ethernet 10/100Mbps Network Lan Adapter once told me the USB/RJ45 dongle can easily deliver 80+ Mbps download connection. I tried gigabit adapters also, they didn't work for me even for ASIX based ones. Maybe they will work if there's right drivers. I believe ASIX has GPLed all its drivers. |

Does anyone know what is the performance of this inexpensive USB Female to Male Ethernet RJ45 Connector/Adaptor and what it can do? I don't know if it can be used to turn an RJ45 port (on a router) into a USB2 port to connect a hard drive (with an external power supply) as a storage or even connect a USB Skype Video/Phone to a router hosting a PBX System. |

said by mazilo:what it can do? 80 Mbps = 10 MB/s , which is still slow for file copy over LAN, but good enough or even overkill for VoIP traffic. I didn't try the TomTop adapter, and they probably have no content answer to customer questions as usual, but just as description says its likely to pass LAN traffic from a router's USB port to a device's LAN port ONLY. Anything else would require special drivers installed on your device, and I doubt its circuitry passes power anyway. said by twinclouds:AX88772B chipset based ones can usually deliver 60 Mbps Does it stay cool to touch during operation? |

That's not a USB 2 Ethernet network card, it's simply a USB jack wired directly to a RJ45 plug. No idea where such an adapter would be useful. |
|

May be as an extra Ethernet port from the modem to a 2nd router?  |

I have no idea what you are suggesting. Maybe I should explain more clearly: it's doesn't convert USB signalling to Ethernet signalling. I just connects the wires from one to another.
The only useful application I would see, is if you have RJ45 cabling throughout a house and want to use one of the cables as a long USB extension. However, you would need a reverse converter at the other end (male USB to female RJ45). |

Actually, I said similar thing in the post above yours. But... some modems come with a USB port on the back. That USB port is designed to provide Ethernet access - just rewired as you suggested, probably for some devices which provide network access via USB. So using this adapter would allow to connect a 2nd router if a modem can support 2 LAN devices (which it probably can if having a USB LAN port). Ethernet and USB connections are bridged allowing LAN traffic between USB device and Ethernet LAN. Motorola SB5101 Manual » www.secable.com/S_pdf/sb5101.pdf |

Motorola SB5101 Manual »www.secable.com/S_pdf/sb5101.pdf That's exactly what I am referring to, when I try to point out that the USB port can't be used as an Ethernet port just by using a connector adapter. The USB port on the Motorola modem is meant to be connected to a USB port on the PC. Then, internally, the modem will bridge the USB connected device to the Ethernect connected device(s) as if they were part of the same LAN. Similarly how many wireless routers have separate network interfaces for Wired and Wireless connections, and bridge them together. |
|
| |
Of course. I wonder in what scenarios a PC would need to establish network connection via a USB port (probably when LAN adapter is broken?), and how to setup such LAN connection via USB port on a PC side? |

What seems to be a concern with your test results? I need to read more about HDParm test definitions & methodology. HDParm may also test reading & writing to HDD internal memory as opposed to HDD platters. Anyway, I do know however my USB3.0 Stick is very fast in USB2.0, and a LOT faster in USB3.0 PC card. I tested it in Windows and Linux on a PC pretty extensively. Of course, latest USB3.0 Sandisk is faster in some operations, but it costs 3 times more, not worse the price for me. |

In my previous post, the timing buffer-cache reads on my WD Passport HDD connected to my Seagate Dockstar through its USB2 port is about 400+ MBps. That is equivalent to about 3 Gpbs. If it is on a SATA port, I could agree. But, this is on a USB2 port. |

Excerpt from HDParm Manual:
"For meaningful results, test should be repeated 2-3 times on an otherwise inactive system (no other active processes) with at least a couple of megabytes of free memory.
Cached reads:
This displays speed of reading directly from the Linux buffer cache (RAM) without disk access. This measurement is essentially an indication of the throughput of the processor, cache, and memory of the system under test.
Buffered disk reads:
This displays the speed of reading through the buffer cache to the disk (HDD to RAM) without any prior caching of data. This measurement is an indication of how fast the drive can sustain sequential data reads under Linux, without any filesystem overhead. To ensure accurate measurements, the buffer cache is flushed during the processing of -t using the BLKFLSBUF ioctl."
So my results were 160MB/s reads from RAM while running many other processes, and yours 400MB/s, but the data didn't pass USB port in the "cached reads" test. Did you run any processes at that time, may be you want to repeat tests a few times? |

Your RAM reads are twice as faster than mine. Not sure why, may be due to newer kernel you use, or I need to check RAM performance, or shutdown all processes. Your HDD results are pretty consistent, and show lower read speed compare to mine USB3.0 Thumb that is quite possible, though write speeds might be higher. Below some more tests: USB2.0 Sandisk Flash vs USB3.0 SP Flash : root@DockStar:~# hdparm -Tt /dev/sda1
/dev/sda1:
Timing cached reads: 370 MB in 2.01 seconds = 184.13 MB/sec
Timing buffered disk reads: 46 MB in 3.01 seconds = 15.30 MB/sec
root@DockStar:~# hdparm -Tt /dev/sdb1
/dev/sdb1:
Timing cached reads: 388 MB in 2.00 seconds = 193.64 MB/sec
Timing buffered disk reads: 94 MB in 3.03 seconds = 31.01 MB/sec
root@DockStar:~# hdparm -Tt /dev/sda1
Hence, USB3.0 Flash shows twice faster reads through Dockstar's USB2.0 port. root@DockStar:~# bonnie++ -n 0 -u 0 -s 64 -f -b -d /mnt/sda1

This shows USB2.0 thumb writes at 1.4 MB/s versus USB3.0 thumb writes at 20MB/s through Dockstar's USB2.0 port. It's quite low for the USB2.0 Flash, so may be I need to try some Block Alignment Techniques » lwn.net/Articles/428584/ to speed up the Sandisk Thumb, or remap its partition structure. :) |

Your HDD results are pretty consistent, and show lower read speed compare to mine USB3.0 Thumb that is quite possible, though write speeds might be higher. My HDD is an old WD Passport IDE HDD and I don't suppose it can do more than 50 MBps read. When HDPARM reported that it could go as high as 400+ MBps, that really surprised me. I am glad you brought up the performance of a USB3 memory stick on a USB2 port. |

More details for USB3.0 enthusiasts using them with a Media Server or PBX Switch installed in a WiFi Router. Many router models currently ship with 1-2 USB3.0 ports. They are equipped with more powerful CPUs allowing writing to disk at higher speed, though not close to max US3.0 spec speed. However, there is an interference issue btw USB3.0 router port and 2.4GHz WiFi Router spectrum range that usually results in significant WiFi connection speed drop or interruption, especially when data is transferred btw the router and attached drive. This issue doesn't affect 5 GHz WiFi spectrum, and neither USB2.0 ports in a router.
