(Sorry missed a bit)

Running on cable whilst downloading 7 files.

Not had any uploads yet.

Cheers

Thanks for the information. You should run fine on a machine like that (as you seem to be).

1.4 does run considerably faster than 1.3, so I'd recommend giving it a shot if you have the time (remember you have to reinstall LimeWire after installing 1.4 to get it to recognize it, unfortunately).

We've not heard of any speed differences with LimeWire between the Intels and the Athlons.

Thanks again. Any more info from others would be great too.

On my computer (WinXP, 384mb Ram, 700mhz athlon), LimeWire takes up 37 megs of ram without any files downloading. I am sharing 36 files and am a leaf.

Is this normal and is anything being done to reduce its footprint?

afisk April 19th, 2002 02:20 PM

LimeWire generally has a high memory footprint, although it's usually not quite that large. There are some things we can do to reduce its footprint, although the larger issue is big footprints with Java programs in general, which we don't have control over.

PIII 500
384MB RAM
RoadRunner Cable

I was sharing 1500+ files. I changed it to 120 and set the upload slots to 0. There is no change in CPU loading.

I have selected "Disable Ultrapeer" on the Speed Tab in Options... There is no change in CPU loading.

I maintain 10 connections. I dropped it to 5 and it does seem to have dropped the CPU loading some.... it's fluctuating between 25% and 70%

Thanks for all of the info everyone. We need to know a couple of things:

1) are you running as an UltraPeer when you see these CPU percentages (you can tell you're an UltraPeer if you have connections labelled as "leaf")

I believe UltraPeer, but I'm using 2.2.0 and the connections say UltraPeer and sometimes "0.4."

2) how many files are you sharing? do you see CPU usage go up if you share more files or down if you share less?
Normally several thousand. The fewer I share, the lower the CPU utilization as shown by the Kernel Toy WinTop on Wi***.

3) how many connections are you maintaining (in the connections tab)?
6 connections

4) how fast is your web connection?
DSL, 640 down, 272 up

5) how fast is your machine (CPU)?
PII 450, overclocked to 500

Thanks very much.
I'm using the JRE 1.4.0. Tested with an optimized CVS build of 2.4.0r. The CPU use is high even with no uploads or downloads.

I have 850MHz Athlon, 512MB, Win XP Pro, Limewire Pro 2.3.3, Java 1.4, sharing 2000 files.

Doesn't matter if I'm an ultra peer or not, javaw.exe averages 60MB of RAM!!
The minimum is 30MB and the most I see is 70MB, but 60-65 seems to be the most common.
CPU usage is between 0 and 40% although it jumps to 100% from time to time.

I have more trouble with slow downloads
 
I used bearshare which maxed out my system resources. (it doesn't help that they install ad ware) My CPU usage is low. Around 20% on average, spiking at instants, but compared to BS which sat above 90... I find downloads slow, extremely slow for how fast my connection is.

100% usage
 
I have a 667MHz intel processor and just installed Limewire last night. I love to be able to download music but the software uses 100% CPU time. And when it does that is is reading the harddrive. I hae even disconnected from the internet and found it does not matter. Whatever this program is doing it is very frustrating.

Re 100% usage
 
It uses 100% of the CPU and grinds the disk for a while at startup as it's scanning your shared files and getting the bitrate of MP3s. It should go down after it's done with that. If you have a large number of files shared, the CPU usage could jump up fairly high as incoming searches are porcessed.

Hopefully the LimeWire developers will start writing a database of your shared files to the disk in new versions or LW so it doesn't have to scan them all at every startup. And I hope they figure out a way to reduce the CPU usage for people with large libraries by either doing whole word searches instead of partial matches or maybe using native C code for the search word lookup.
