Speeding up WinRAR?

I think WinRAR stores the data in the system TEMP folder anyway, then copies it to the destination drive, so making the destination a different drive would only affect that copy step. I can't remember, it's been a few months since I used WinRAR instead of 7-Zip. That might still be significant, but wouldn't affect the lag of the unpacking process.
At the very least, even without a multi-threaded application, the system would respond better with dual-core since one core would be free to do other things while the other was busy with the extraction.
I just upgraded from an XP 2800+ though, and I don't recall all that much lag on that system when using WinRAR even on extractions where the destination file was a couple of gigs, made up of 2 to 10 parts.

A faster CPU is the main thing that will speed up compression and decompression. Dual core would be ideal.
HT or DC helps significantly regardless of WinRAR's multithreading option however that does give a li'l boost. It's been a long time since I used a Celeron and the main reason I did so only temporarily was that despite the low price and equivalent single task performance, the multi-tasking was poor compared to what I had become accustomed to with HT. Athlon 64 were touted as high performance but that likewise can really only apply to a single task such as a game. DC should make an even greater difference than betwixt SC & HT.
Large media file archives may not even be stored with compression in which case CPU usage is minimal and the main limiting factor is storage performance. Unarchiving is then just a copy operation and will be twice as fast to a seperate HDD. So your lag could originate from either and be exacerbated depending upon the further demands of concurrent tasks.
For the temp folder setting, you will notice there is a toggle to only use it for removeable disks -thus speeding up regular HDD un/archiving. Presumably the "current folder" it then uses is the destination.

The biggest thing will be to use a second hard drive on a different channel. Dual core would provide only a small benefit in comparison to getting another drive.

no, you'd still be lagged by the single cpu. one core dealing with harddrives+rar other one is free. unless you need to heavily access that drive too with another app then its going to be smooth sailing. yes u can force it to be lower priority or just set it, but it slows progress than

I know, I'm no fun. 🙂
I myself am trying to justify an upgrade to dual core, but it's rather difficult, especially since I seem to have just solved my stability problems, courtesy of a 0.025v boost in my CPU voltage. Though they are still crazy - it's set to 1.65 in BIOS, but MBM reports a crazy range from 1.55 - 1.62.

Well according to the previous posters in this thread it's quite obvious they have experience with dual core processors and using compressor software and I will believe people who have had first hand experience with it. So It would be safe to assume that a dual core processor would indeed actuall help or benefit one if they're performing heavy unrarring duties.
sigh.. so much beating around the bush. The issue with winrar / quickpar (for those who use it) will also be the harddrive bottlenecking it. Want to unrar faster, use raid0, only when compressing will a good cpu really help. But as always the slowest thing inside the PC for many years now is the harddrive. I upg from 2500 athlon xp / 1gb ram to dual core opt 170 / 2gb ram expecting winrar to go faster. It was originally taking me 7-12 minutes to unrar a dvd on the old rig. After the upgrade to DC and more ram, still similar times. Got raid0 and then I truly saw it shine. 3-4 minutes per dvd unrar. BTW raid0's performance is hard to find elsewhere, it wont make things super fast, windows loads in the same time as before (maybe barely faster, never noticed a real difference) But when working on huge consistant files like a rar file or quickpar, you can really see the performance of raid0.
