WordPress sites poor performance on Nginx

  • Hey guys,

    All my wordpress sites have a very poor performance using Nginx. It takes almost one minute to load a page. Guess this has to be related with Nginx configuration via WHM/cpanel.
    I got 8GB Ram with 6 processors under the hood.

    What are the best config settings?

    Thanks in advance!

    WordPress version: 4.1
    Plugin Nginx:
    Nginx Admin (v5.0 Stable)
    (Nginx Version: (1.6.2 )

    CENTOS 6.6 x86_64 virtuozzo – host
    WHM 11.46.2

  • It is not about ur server. my 512mb ram working perfectly with my music streaming site with double wordpress and some really powerful plugins. I think it is about nginx or some plugins or theme messed up. I have had some horrible experience (no offense) and found there are too much things to do manually to make wp 100% working in nginx. It messed with permalink, CHMOD, directories and bla bla.. my 3 days was nightmare. Then I installed Apache again. But if u are a pro then nginx is best. If ur site takes 1 minuet (!) with a normal internet connection then I afraid cache and other optimization plugins wont help. A wp sites load time is 2-10 second avarage.
    Some suggestion (not professional):
    *disable gzip.
    *increase process numer.
    *Double check internet connection, plugins,theme.
    *be careful about Js from 3rd party site.

    Thanks Sykat for your help.

    The weird thing is that all these wordpress sites worked fine and fast on my former provider with Nginx also installed. And I made no changes to my plugins…So theme- and plugins issues can be ruled out. The problems occured after I migrated to my new provider. I guess there are config problems with Nginx or my current server.
