I am moving from a public web hosting company to VPS. And I'm trying to find the best configuration for my system.
For 1 specific table with half a million records, 1 query, which takes several seconds on the previous server, now takes minutes.
I am trying to improve the response time of my server, so I bought more memory (I have 2 GB of RAM, and I can still buy more resources, if necessary, and 2 cores). I also "tricked" by copying my.cnf of the old company to my VPS:
[mysqld]
read_buffer_size=8M
read_rnd_buffer_size=8M
sort_buffer_size=32M
innodb_additional_mem_pool_size=503M
innodb_flush_log_at_trx_commit=1
innodb_log_buffer_size=16M

[mysqldump]
quick
max_allowed_packet=16M
[myisamchk]
key_buffer=64M
sort_buffer=64M
read_buffer=16M
write_buffer=16M
The problem is that the request is still slow and the server is not using the available memory!
total used free shared buffers cached
Mem: 2002 1986 15 0 6 1079
-/+ buffers/cache: 901 1101

Any suggestions?
