WinRar slow and low CPU%Does anybody else have a problem with WinRar running slow. I get at max 5-6% cpu usage. I extract large files ~700 MB.
When I use 7-zip it takes about 1/8 the time and my CPU is pegged at 100%.
I have tried, what I think is every appropriate option, like dual core ect...
Anybody else have this problem and maybe a solution? |

did you check if your AV is accessing/checking the file?

Thanks for the reply.
No I don't have AV software on my computer.
I have windows XP sp3 if that helps. Also, I finally found some other forums with the same topic, and the conclusion seems to be you can't do anything about it. I hope that is not the case. |

My WinRar is pretty fast, and not on a dual core.......and I unrar 700mb files all the time. It should not be using full cpu either......(I don't believe).
I am using an older (different) version though.... |

Check the settings/options, see if it is being used in low priority mode. Also check where the temp folder being used for temp files is....is this a slow drive? If so move the temp folder to a faster drive. |

said by Inflex:Are you disk bound? IE, is your hard drive ligh lit solid? Maybe so, I recently switched to a WD green edition HD, 5400rpm vs 7200 on my old one. But that does not seem to make sense, because I can copy a 700MB file much faster. Also, I was incorrect about 7-zip, it too only uses a fraction of my cpu % when opening rar files ( I was thinking about compression - sorry I've been not sleeping well...) but still seems to be much faster. |

If so move the temp folder to a faster drive. Yes, as it happens I have a 5400 and 7200 drive on my computer. But If i just change the location of the temp folder, would it not have to copy from my desktop to the destination drive first? |

Do you have indexing running on your Drives? It should be off for faster performance and use a better search utility like Agent Ransack.
Do you have the drives setup with write cashing properly?
Do the drives show the correct DMA Modes?

Ok, I checked that and indeed indexing was on. I turned it off, seemed to have a very slight speed up. Also I am on Sata so all the DMA modes are grayed out. |
