[gentoo-amd64] Rsync server performance problem solved

[Peter Humphrey]

A few months ago I described a problem in which my gateway box, acting as an 
rsync portage server to my desktop and portable boxes, was taking several 
minutes to create and transfer the file list. The transfers of files to 
synchronise the local portage database with that on the server worked just 
fine, however.

It turns out that the 256 MB of RAM in the server wasn't enough, since as soon 
as I put in another GB it just flew - about one or two seconds now for file 
list transfer, which is a factor of 50 or 100 better.

The box does run BOINC clients, but at nice 19, so I though that shouldn't be 
a problem. However, I now remember that my BOINC parameters included a 
leave-in-memory-while-inactive option, and I suppose that must have been it, 
though I don't know how the kernel would operate with that setting.

Hope someone finds this interesting.
