for hosting many websites on one server,

what is the best setting to set for the

xcache.slots and xcache.var_slots? is 8k enough?

and other settings like ttl?

also what does readonly_protection really do?

focus on
xcache.size
xcache.var_size
and check other settings only if you have trouble

try to set xcache.size = 256M, and see xcache-admin page (install it 
first) after xcache is enabled for 1 hour or so. you'll know if the size 
is too big or small

Also, if you're running apache, or fastcgi processes are common between 
the sites, and/or you're not restarting often, consider flushing cache 
periodically to prevent cache pollution
- with scripts from websites that are rarely visited
- or scripts that no longer exists on the disk (because they are 
dynamically generated/removed by CMS or just simply not there, ie. 
removed by developer).

#!/bin/sh
for w in www1 www2; do
    for c in 0 1 2 3; do
        wget -q --http-user=user --http-passwd=pass --post-data 
"type=0&cacheid=$c&clearcache=Clear" -O /dev/null http://$w/xcache/
    done
done
