Hi. I've been a user of WP for +4 years now, but now I'm using it in my work as a news CMS with a serious problem: the server freezes too often.
- Our website have +/- 18.000 unique visitors and 45.000 pageviews per day.
- We publish an average of 80 posts (news) per day. Now we have +6.800 entries.
- Yes. We had a lot of plugins, but now we disabled all but 6 (Akismet, Audio Player, FeedBurner FeedSmith, User Locker, vSlider and WP Super Cache).
- We use Comfy as theme.
We have a modest server (Quad-Core with just enough RAM under a 10 Mbps line) that makes it suspicious. However, the odd thing is the server won't fall on peak hours only, but suddenly at noon or midnight when everything seems fine.
The load of the server goes from 2-4 to 10 and then to 50 at a jump, and the server hangs. We have changed it 3 times to discarg hardware issues.
Now, I have read that the last version of WP (2.8.4) have CPU problems. You know if this is real? What can I do?
You can see the website (if it's running ¬¬) on http://www.radiobiobio.cl
Any orientation will be very much appreciated.
