Even if MS Word was made out of 100% java it still work , Limewire remember recieves way too much traffic...

It could be about the sharing files thing.


Well at the end of the day I am happy with another P2P .

Hmmmm I'm in agreement with Peerless.

I run LW pro 4.8.1 and run as an Ultrapeer with 62 connections, and also have no such issues.

Please try to understand , LW used to work until one day it just would'nt load then I replaced java 4 times and upgraded to LW 4.8.1 and then everyone has issues.

I have a question , When limewire 4.2.6 was avaliable were there more or less errors posted in this forum?

Peerless, fabian: does it work as well with a CPU half as fast, half as much RAM, and the free version of Limewire? Maybe this is something that works better in pro (I guess to try to make people pay up, but it just makes them go to Shareaza instead); or maybe you just don't notice anything because it's only using half your 3GHz CPU.

I reinstalled 4.2.4 to see if the problems with the CPU usage was the same. It's not taking up 99% as 4.8.1, but it's still very slow to respond to any requests such as clicking on the Toolbar, searching....etc...

Not quite sure that it's LW now...starting to believe that it's a java problem.

I have noticed several patterns in this behavior.

1. Limewire cpu use spiking often occurs right after a download is finished. As if the occasion calls for major number crunching, even if the "verifying" and "saving" stages flash by quickly. After a few seconds LW slows to a crawl for a minute or two.
2. Performance on my machine seems to degrade drastically if LW's memory use climbs above about 100M. If it's 80 it's very responsive. If it's 100 it's unbearably slow. I'd suspect thrashing except that the machine has over a gig physical ram FREE, NOT IN USE when this happens! With 2GB in the box performance should degrade much more gracefully, and only when total mem use is a LOT more than just ~6-700M total commit charge. Who designed this piece of ****?
3. What the FU&! is it doing that can saturate a 3GHz dual-core CPU? Nothing an event-driven application ought to be doing, methinks. And at a priority equaling the event-handling for the UI, at that, rather than at a much lower one.

Hey Guys
I had the same problem! I uninstalled all of Java completely and then LW.
Then just ran install program for LW and it installed Java as well, now everything seems fine!

You could try to start Limewire by commandline with the following arguments:

java -Xmx255m -jar LimeWire.jar (in the Limewire directory).

it seems LW runs with the default heap-limit of 64mb (+ ~16mb for java-runtime itself) and of course if LW gets too close to this limit java is Garbage Collecting over and over which affects performance and could even lead to a crash of LW :-(

good luck, lg Clemens

That solved my performance problem, but now magnets start LimeWire w/o the new heap size. Where do I change this default heap-limit for any instance of LimeWire or for any Java application?
