The system runs on 3 servers - back, front(apache) and images(nginx).
I think of something like nginx does with static files.
To load only once the script and run it from few workers, so the memory footprint will never increase.
If it's possible ? Stable ? Production ready?
For now the server serves about 150 request per second, the cpu is low and IO is ok... seems that only memory is a bottleneck.
(I will read about memcache)
Thanks.
