|  [BOINC] Projects crunch extremely slow.
I have an older Dell, 1.7 running XP SP2, single core.
As of late its been running slower then molasses when crunching a projest.
It starts out running at 100% cpu but within 5 min it'll be jumping from a low of 20% to 70%
Task manager will show 'system' fighting for the cpus.
Process monitor shows nothing running except Boinc.
Running Boinc v. 5.10.45
If anyone has any ideas on what may be causing this I'd appreciate the input.
Thanks, Dan

| In the process tab of Task Manager - you can sort by process name (should be approx 20 there at a minimum or by CPU usage. When BOINC goes to less than 100% you should be able to see what the rest goes to - even if for a short burst.
There are other process monitors that go deeper that can claso be used. |

Runs with spikes up to 60% cpu.
Only stops when I shut down Boinc.

Hmm I've jumped ship on shitty microsoft and went to linux. Runs real well. Just got boinc running now and it seems wacky. It takes about 3minutes to get 1% on the WU but it says i'm 24 hours to completion which seems really odd. Ought to be more like 5-6 hours.
Maybe I just need to let a couple work through before "to completion" works properly.
Perhaps that's the same issue you are having?
Are you even sure you're going slowly? How slow is your work going? |

| When I first start it runs great, at full spend.
After about 5 min. system in task manager starts eating up to half the cpus, slowing down the program I'm running to a crawl.
Tried Process Exployer and Process Meter without luck to find what's eating up the cpu's.
Thanks for the reply.

You said that the system process in task manager is hogging CPU. In ProcessExplorer, right click the system process and select properties. Then check the thread tab and see what in the system process is taking the cpu. |

Maybe I just need to let a couple work through before "to completion" works properly. Until you've gone through about a month's worth of WU's, your estimated completion times will always be high, as the project needs to adjust under Linux now.
When I first started under Ubuntu, 24+ hour estimates were common for me, and now my completion estimates are down to between 14+ and 16+ hours, on a P4 3.2ghz HT single core system. (This system is like 4 years old!!!)
Sit back, relax and enjoy the new OS and let BOINC get adjusted to the new diggs.

I played with it and suspended several that were running without incidence.
At this time system is showing 0 cpu usage.
Hope it stays this way now.
TE and everyone else who responded, I thank you!

Sounds like you're infected.
ntoskrnl.exe is a critical process in the boot-up cycle of your computer although should never appear in WinTasks whilst under normal circumstances Note: ntoskrnl.exe can be altered by the w32.bolzano and variants. If this process appears in WinTasks, please update your virus definitions immediately.
Also my boinc is running well now. |

| I Googled ntoskrnl.exe. Seems there has been some problems with this and AVG which I was using on that computer.
If you started a scan the first thing that showed was the 4 files in system as changed, not infected.
The key to fixing this is deleting an AVG file.
I got it fixed but installed Avira free instead.
By the way, no infections, system clean.
Thanks, Dan

From Wikipedia, the free encyclopedia
ntoskrnl.exe (and ntkrnlpa.exe on systems with Physical Address Extension support) is the kernel image for the family of Microsoft Windows NT operating systems. It provides the Microkernel and Executive layers of the Windows NT kernel space, and is responsible for various system services such as hardware virtualisation, process and memory management, etc., thus making it a fundamental part of the system. It contains the Cache Manager, the Executive, the Kernel, the Security Reference Monitor, the Memory Manager, and the Scheduler, among other things.

By the way, no infections, system clean. Thanks, Dan Even viruses that are detected by antivirus scanners can be changed enough to become immune to being detected by antivirus scanners. It sounds like you are sort of using an antivirus scanner as your basis of thinking you are safe. I dunno. Windoze is so brutally at risk it's sad. All up to you though.
Might I plug UBUNTU »www.ubuntu.com/
Virtually immune to viruses and spyware. There has never ever been a report of a person being infected by a virus. The OS is also quite popular among the different linux distributions.
Then you will get very very high levels of performance. |

| If there is any doubt I will use several scanners, not one.
I am confident the problem is fixed.
By the way I don't think IE is that bad if it's secured properly.
In the last 10 yrs. I have never had a virus, trojan or malware of any kind.
And no, I don't mind you plugging UBUNTU.
Have thought about trying it soon.
We shall see.
Thanks for the response.

All the power to you. I'm personally very paranoid because I used windoze for far too long.

When I read that my face I'm sure went all red and felt like an atomic bomb blew up in my face. ARGGGG. IE is terrible. There's like 20,000 different viruses and exploits or something along those lines in IE. That's different types... how many are spread around on the vast internet and replicated... my my flying spaghetti monster please bless him with your noodly appendage because of how broken IE is. Firefox on the otherhand has a security flaw... person posts fix. It gets fixed.
Open source allows for white hats to do their magic and some loyal black hats also. Meaning there are far more educated people looking to fix the browser then damage it. Completely unlike IE. Who probably has all black hats and some white hats out to prove a point looking to bust IE.

It's no problem. You can download it free. 700megs or so. Burn to a cd and you have a Live Cd. Meaning you can boot into ubuntu and check it out without damaging your computer in any way. If you have a nvidia video card gaming and such will be highly likely to transfer over at the same performance if not better.
Windoze can go the way of the dinosaur and you will never see Mac vs Ubuntu commercials because Ubuntu is free and thusly cant afford commercials and Mac cant find a single thing that makes MACs superior. |
