Apart from adding cores, there are 2 things I'd suggest looking at
- are you using an opcode cacher? APC ( install via pecl to get the
latest ) works really well with php in fpm... allocate plenty of
memory to it too
- check the bandwidth at the network interface. The usual 100Mbit
connection can easily get swamped by a graphics rich site - especially
with 250 concurrent users. If this is a problem, then look at using a
CDN to ease things.
Thanks for the hints.
The strange thing is that unix load does not seem to be over-strained
when this performance deterioration occurs.
APCu seems to be enabled:
extension = apcu.so
apc.enabled=1
apc.mmap_file_mask=/tmp/apc.XXXXXX
All other params are default.
The network interface is Gigabit and should not be a problem.
We'll add virtual RAM and cores. *Any other suggestions? *
I wish there were a tool which benchmark/analyze the box and running
services and produce suggestions for all lemp stack config: mysqld, php,
php-fpm, apc, nginx! Some magic would help!!
Thanks,
Nick
