planet – resource use

I just noticed that /usr/bin/planetplanet is using about 120M of RAM. This isn’t currently a problem as I’m running it on a machine with 256M of RAM, however I would like to run my web server on a 96M Xen instance. 120M for planetplanet is probably going to cause bad performance on a web server with 96M of physical RAM allocated.

This is a serious problem for me as the Xen server in question can’t be upgraded any more (the motherboard has as much RAM as it can handle).

Are there any other free syndication programs that use less memory?

Are there any good free syndication services that I could use instead of running my own planet?
