LimeWire 4.9.30 + explorer.exe = 100% CPU usage
 

First off, I just wanted to say I've been a long time LimeWire user and supporter. I recently upgraded to LimeWire 4.9.30 basic and have been having some issues with CPU usage. Actually, my computer was also "freezing up" on the previous version of LimeWire as well. It usually only happens when downloading a file larger than 200 mb.

Edit: I'm running Windows XP with SP1, ZoneAlarm 6.0.667.000, Java2SE 1.50, cable modem, sharing 2 gigs of files, P4 3.0GHz CPU, over 200 gigs free on my SATA hard drive and I have a gig of Cosair TwinX4000 memory. I seriously don't think it's a hardware issue. I built my 'puter last year and it's still pretty fast.

I'm not sure if LimeWire is having memory leaks or what. I recently formatted and did a clean XP install and still have the same 100% CPU usage problem. Like I said, it only seems to slow my computer down to a crawl when downloading large files. The only thing I can think of that might be causing the problem is that I have a habbit of leaving open my Shared folder and Incomplete folder when running LimeWire. Ya know...so I can see what I've downloaded/downloading. ;)

I'd greatly appreciate any help.

Thanks,
Swanky

This just a shot in the dark. Check out the post in the link below by robobarbe see if anything rings a bell there.

having a windows explorer window open with lots of files with meta-data seems to cause the cpu to rapidly use up 100% of cpu. its because of the heavy harddisk reading.

downloading large files while doing this only helps to increase the harddrive activity because of large chunks of data being written and re-checked by limewire.

my suggestion is to defrag your harddrive after downloading a few rather large files. after downloading lots of small files, a defrag isnt necisarry, but may help improve performance. my extra advice here is to have a defrag scheduled atleast once a week.

I tried the defrag method, but it's still randomly causing around 50% usage with LimeWire.exe and 50% with explorer.exe. Like I said before, I don't think it's a hardware problem. I'm running a brand new Maxtor 300GB SATA with 16mb cache. Games, Photoshop, and Azureus run flawless so I don't think it's lack of memory either. Same problem on the new drive like my old one. I'm not running any other programs when the freeze happens either; just LimeWire and two windows folders. *shrug*

When my computer starts freezing I either hit reboot or let it idle for 5-10 minutes and the CPU usage will finally drop down to 2-3% on both programs. Actually, this might be a shot in the dark, but I'm thinking it could be a codec issue. I have the K-Lite Codec Pack 2.54 Basic package installed. Should I try the Full package version? That might explain why explorer.exe is having high CPU usage (missing codecs), but I still don't understand why it would cause LimeWire to skyrocket as well. Perhaps I need to uninstall/install LimeWire and Java over again.

LOL, I blame WinXP! I'm learning Ubuntu Linux on my old 'puter so by the time Vista comes out I'll be switching to Dapper Drake / Breezy Badger; whatever they plan on calling it. :D

It coul be a bad Java install you might want to uninstall LW and Java then manually install both don't use the online installers. Save them to your hard drive then install them. The link below has links to Java in it.

You can blamb windows if you want. But I like Windows it's not the problem.;)
