How to decrease Server load on VPS

[Spartan]

Hello guys ,

i have a wordpress blog with over 55k posts

I have no scheduled posts so most likely this is not a cron job problem

Blog has around 55k tags & 100 categories.

The server load is usually around 1-2 and some times it goes upto 5-10.

i have installed WP super cache.

Other than that i have installed and activated following plugins :
Yoast SEO,Robots meta, Disable search , Quick page/post redirect dev, .html on pages

i have already tried disabling all plugins and enabling one by one, it didn't helped and most likely plugins are not causing the server load.

i have installed nginx over apache on VPS.

Due to the load issues my site also loads slowly and most likely this has resulted in drop of traffic by Search engines.

i am not able to find a way to solve this, if any one has dealt with such an issue any guidance would be appreciated.

Thanks

double check the load caused by WP super cache.

Can you give us your daily traffic and server spec?

Server load is depends of your traffic and size of your database...

write a bash script to kill over loaded process. (ex: httpd)

I installed it. It suggested a few things like increasing memory for some variable which I did. The fluctuation of load has reduced considerably but I will analyse the load for more time and will post here if it causes problem again. Thanks a lot for this guide

How do I check the load caused by a particular plugin? I had read about that core control wordpress plugin, but I'm kind of scared to install more plugins on that site. So is there an alternative?

Around 3k traffic.

Thank you

Any guide to find over loaded process automatically?

I know to to kill, restart etc. but I have never written such bash scripts before. Any reference is appreciated.
Thanks.
