Title: Info about performace
Post by: Pazzeo on July 04, 2009, 08:33:58 PM: Hi all I'm trying to compile amule for my router, mips-linux, that it has only 16Mega. So I want to know if the performace will be so terrible using amule on this device.
What do you think about?

Thank you very much

You might have success with swap, but it would run very slow.

So in this situation it'll be slow? Slow is during the download the file? Do you know in what device I could have best performace?

Thanks a lot

I believe the speed while downloading should be acceptable. The problem is too little memory, so that it would be swapping constantly.

But: When it is hashing, it will take a very long time and your router will probably appear frozen during this time.

There are people running amuled on a nslu2 (32MB RAM + Swap, I believe) and freddy77 (http://www.amule.org/amule/index.php?action=profile;u=15205) contributed patches to the current developmental version to reduce memory usage - I believe his target machine had 64MB without swap.

The router apps running that use the memory a lot.
i experienced.

Tries that. aMule on NSLU2 is barely useful - KAD should be off, hashing killing nearly everything, and so on. Swap on nslu is very very very slow thing (arm cpu+usb connection).
