hello Micha,
i think that noone can tell you much without more information about your
system. roughly i would say that you could change the following parameters:
shared_buffers = 1024MB -> 6GB
work_mem = 256MB -> 30-50 MB
effective_cache_size = 5120MB -> 16GB (depends on whether its a dedicated db
server or not)
kernel.shmmax=5368709120 : now its 5GB, probably you need more here, i would
put 50% of ram
kernel.shmall=5368709120 you need less here. check he shmsetup.sh script for
more info
autovacuum off -> on
