Magento VPS Optimisation

Hi Guys, I have a test VPS with 30GB ram running SSD's and 4 quad cores, so this VPS should be a best and easily run Magento loading pages well within 2 seconds. Static pages are fast, and load just over 1 second each, but as soon as anything query driven, the time shoots up. I have done some optimisation, but unsure what else I can tweak. I'm running Apache 2.4 with PHP 5.5. I have also enabled OpCache to try and speed things up a bit. Here's my httpd.conf:

# These can be set in WHM under 'Apache Global Configuration'
Timeout 60
TraceEnable Off
ServerSignature Off
ServerTokens Full
FileETag None
StartServers 15

MinSpareServers 15
MaxSpareServers 30

ServerLimit 256
MaxRequestWorkers 250
MaxConnectionsPerChild 10000
KeepAlive On
KeepAliveTimeout 5
MaxKeepAliveRequests 120

Here is my my.cnf settings:


[mysqld]
default-storage-engine=MyISAM
innodb_file_per_table=1
max_allowed_packet=268435456
open_files_limit=10000
query_cache_size=100M
query_cache_limit=1M
join_buffer_size=8M
sort_buffer_size = 8M
read_buffer_size = 8M
read_rnd_buffer_size = 4M
table_cache=4096
max_heap_table_size = 50M
innodb_buffer_pool_size = 1G
table_open_cache = 4000
key_buffer_size = 128M
tmp_table_size = 128M
myisam_sort_buffer_size = 64M
query_cache_size = 96M
query_cache_type = 1
thread_cache_size=16
max_connections = 400
wait_timeout = 300

General recommendations:

    Run OPTIMIZE TABLE to defragment tables for better performance

    Enable the slow query log to troubleshoot bad queries

    Adjust your join queries to always utilize indexes

    When making adjustments, make tmp_table_size/max_heap_table_size equal

    Reduce your SELECT DISTINCT queries which have no LIMIT clause

Variables to adjust:

    query_cache_size (> 96M)

    join_buffer_size (> 8.0M, or always use indexes with joins)

    tmp_table_size (> 128M)

    max_heap_table_size (> 50M)

I'm not sure what else I can do to speed this beast up? Any ideas?

Install nginx too :) enable cache and compression . That will give some more speed.

This is something i am looking at doing, but trying to get the most out of what is currently installed.

Hello :) You can try lowering the query_cache_size value in /etc/my.cnf to "64M" to see if that makes a difference. Thank you.

Thanks for the suggestion, that seemed to shave off around half a second or so. Did a bit of reading up on query_cache_size, and more is defiantly not better on this setting (although mysql tuner suggests going higher with this value). I'm thinking of running php in FCGI mode to get things like opcache working with Magento properly and then install Memcache. I did try NGINX, but I don't really want to take things away from EasyApache (after installing NGINX previously and then trying to rebuild apache after a corruption left me with a load of errors). Also NGINX was a nightmare to set up especially with an SSL.
