Reduce power consumption

Added by Mario Luzeiro over 11 years ago

Hi,

I would like to reduce the power usage of my redmine server. any hints?

right now I have the Top causes for wakeups:
mysqld.bin __mod_timer (timeout_func)
and
redis-server __mod_timer (process_timeout)
and
httpd futex_wait_queue_me (hrtimer_wakeup)

how can I reduce this cpu usage? and so on.. ?

thanks

You're joking, aren't you? The purpose of a server is that all components of the stack (http server, application server and database server) deliver data as fast as possible...

This is a personal server used for me. I only be using it one or twice a day. I don't mind to wait seconds for the first click, since I will pay the energy bills.
I want a real time server, real time means that the data is provide to me in a useful and meaning time.

While I think tweaking wakeups might reduce overall power consumption, the effect will be so minor that it probably won't even be gaugeable monetarily.
