I have read this whole thread on system slowdown. I have a similiar problem but do not have high CPU utilization.
I have a 1.8 ghz p4 500 ram running xp pro and LW 4.8.1 pro, java 1.5.4 and cable connection.

I have have max uploads and downloads set to 4 and have followed the previous suggestions for LW setup.

LW runs about 4 to 15% cpu and 40,000 - 60,000 memory.

It seems to run fine when first started and then as the day goes on it progressively slows my machine down. Switching between active windows takes forever as the graphics slowly are displayed. The disk drive goes crazy like a lot a swapping is going on. Stuff is downloading great, but I sacriface using my machine for anything else because of the horrible performance.

It seems that one I switch to and active appplication, say Lotus notes, and it gets caught up, that app is runs better until you switch to another app.

It is really bad if you let it lock out from inactivity. It takes for ever for it to wake up and log back in.

The machine runs fine once I shut LW down. Azureus had the same problem but worse, that is why I tried LW.

There must be something we are missing here. Any suggestions?

An update on my previous post. I have since followed the few tips that suggested that you close any LW windows you don't need open (all in my case, search windows and such) and CLOSE (not minimize) the application window so that it minimizes to the systray. Since doing this, my system does perform much better. I still have some delay, but not as bad as before. Seems funny that such minor changes can have such an impact, but they did for me.

This is strange but ... if you open and then close the library tab, LW performs better than if you have it closed from the start of a session. The hanging-for-a-bit-after-every-download problem goes away.

If you exit LW with the library tab hidden, and then restart, and have tens of thousands of files in the download directory, it will freeze for a while after every completed download. If you then show the library tab and hide it again, this freezing behavior stops occurring for the remainder of the session.

Strange.

Not that it's relevant, but nVidia.

It's strange, here on my comp Limewire is VERY slugish I can't search or download because it goes to 100% CPU Usage, and I have a old laptop Celeron and I have installed there and it works out of the box

BTW I have too a Nvidia card...

Shouldn't matter. I know enough about Java to know that there's an abstraction layer between Limewire and any dependency on what the graphics card manufacturer is, and enough about Windows to know that on NT/2K/XP, there are two abstraction layers between Limewire and the gfx card.

Anyway, I'd expect the gfx card to possibly be a problem for 3d games and not much else. Certainly not a traditional gui app whose only graphics are command buttons and text labels, one that doesn't do anything at all fancy with graphics. And even if the card gave a game problems, I'd expect having up to date drivers to fix them. And I do have up to date drivers, the better to play Quake 3 with.

Actually there have been issues with graphics cards. eg: The way to fix the Blank screen on startup There's also been laptop issues which involved needing to upgrade their intel drivers, etc. And also these probs

Also for some people, they've found the beta version to be a little more system friendly. But how it performs on particular systems, as with the 4.8.1 will of course vary. Pro users can downld the pro beta from their personal downld page. For everyone else from here http://www.limewire.com/english/content/beta.shtml

Doesn't make sense. A 3d game being wonky with a problem video card or old/buggy drivers I can see, but a normal gui app? If there was a problem with my card or drivers that serious, wouldn't the web browser and every other gui app be affected as well? And there are no graphics problems -- this is generic slow down, excessive RAM and CPU use, sluggish UI etc., not visual glitches or out-and-out crashes which is what video card problems normally produce.

And besides, it can't be my video card because if it were there'd be nothing I could do about it. Everything is fully up to date, drivers-wise, and I certainly aren't about to spend ~$200 replacing the actual card, given that it works perfectly with everything else on my system -- and I do mean everything. Including actual graphics-intensive games and the like, as well as normal gui apps.

If it is the graphics card, it isn't the card's fault -- it's Limewire having a spurious dependency on it, and not merely demanding that it work properly but even being gratuitously incompatible with certain brands, manufacturers, and chipsets. Which would mean you're using JNI to do low-level graphics calls and even trying to bypass the NT kernel HAL, which is a big no-no. Just use swing and forget about anything fancy!

Agreed. This is a Limewire bug, even if it only gets provoked when a certain video card type is in use. Nothing should fail to work properly due to choice of a video card, so long as the video card is good enough for the demand placed on it (i.e., you're not trying to play Doom 3 on a GeForce 1) and the card is physically working and the drivers are reasonably up to date (at least as recent as the application).
