[CentOS] Doubled up RAM to 32 GB - now how to speed up a LAPP server?
Dear CentOS users,
I run a small Facebook game at a CentOS 6.3 machine
with PostgreSQL 8.4.3 + few PHP scripts + 1 Perl daemon
and even though the server worked ok,
I've suggested my users to double up the RAM
to 32 GB and they have collected money for that.
Now my problem is that I don't know, which knob
to turn and how to really use the additional memory.
Below is my top output at the peak time (evenings) -
as you see, 27 GB of RAM aren't used:
# top - 18:47:55 up 23:12, 2 users, load average: 2.17, 2.31, 2.56

What I've already done:
/var/lib/pgsql/data/postgresql.conf (local connections only)
max_connections = 10
shared_buffers = 4096MB
work_mem = 16M
/etc/php.ini
memory_limit = 300M
[PostgresSQL]
pgsql.allow_persistent = Off # because I use pgbouncer
/etc/pgbouncer.ini (local connections only too)
max_client_conn = 600
default_pool_size = 80
/etc/httpd/conf/httpd.conf (didn't modify yet):
<IfModule prefork.c>
StartServers 10
MinSpareServers 8
MaxSpareServers 30
ServerLimit 512
MaxClients 512
MaxRequestsPerChild 4000
</IfModule>
Any suggestions please?
I was actually hoping that Linux would use the additional
memory for caching disks, but this doesn't seem to happen?
Thank you
Alex

[CentOS] Doubled up RAM to 32 GB - now how to speed up a LAPP server?
Sorry a typo, I have
max_connections = 100
in postgresql.conf (I was advised not to change that number).

How much GBs do your database and your files do take? If you have 100 MB of files, the OS won't cache 30+ GBs... JD
