Greedy multisite using too much resources (6 posts)

    Since I went multisite with my 3 webpages, the server on which I host my sites is constantly going down.

    Of the 3 websites one is a blog using quite a lot of plug-ins, the other one is a relatively simple site and the third is HTML only.

    Originally I had 150MB of RAM and 15 processes assigned. When I was still on single WP installation for the blog and separate HTML website (the third one didn't exist yet), I had no such problems.

    Since I went multisite I upped my RAM allotment by 150MB, but it still keeps crashing.

    The traffic didn't go up much and it's still very low.

    I asked my provider and he said wp-cron.php accessed the server 8300 times and admin-ajax.php 6300 times today by 2PM.

    Anyone has any ideas what can cause this ?
    The only plug-in I installed after going multisite is 'BWP Google XML Sitemaps'.

    I disabled wp-cron in wp-config and set up a new CRON to call the wp-cron file through URL every hour. Hopefully that'll be enough.
    Also, I'll reduce the frequency of changing the random quotes on my blog, as I think this could be the reason for calling admin-ajax so often.
    I'll see if it resolved my issues when I get my next 'traffic spike'.
    Thank you.

    install wp-super-cache.

    if you have root access install APC cache. and the APC object cache for wordpress.

    that will help A LOT

    I already have WP Super Cache.

    Yeaaah that would really do a number on you!
