PHP torrent tracker configuration

Question

Hi everybody. First i'd like to apologize for my english. I'm from Argentina, and i'm not a good english speaker.

I'm trying to improve performance in a torrent tracker site, here in Argentina (http://www.trackerx.com.ar). But i've been running with some troubles. It has started to work real slow, and hung up from time to time.

I want to reconfigure PHP and Apache, the main idea is to add RAM to the server, and give more memory to php memory_limit.

So, my question is. Do you know how much memory is recommended for a tracker with 15000 peers?

Have you any tip for configuring it, maybe another post, webpage, paper, etc?

Thanks everyone!

Answer 1

I am thinking this should be on serverfault. But generally you should figure out how much memory 1 peer uses, then multiply by # of peers and leave something like 20% headroom. What does the tracker software you use recommend?

Edit I took a look at the phpbttracker+ project, not sure if this is what you are using, but it recommends a p4 1.6 and 1gb of ram for 10,000 connected peers. This is with a 1MBit connection.

Trackers are fairly CPU intensive so throw as much cpu power at it as you can afford.
