How many WP blogs can a dedicated server handle?
 

I have a new box with folowing spec.

Dual 2.8Ghz Xeon(single core)
2Gb RAM
250Gb SATA
2000Gb transfer
Centos 4.6

Let's say a blog have lastest WP installed with some plugins(SEO, super-cache, feedwordpress), unique IP and domain, 200 unique hits per day.
so how many blogs can I run on this server??

I'm going to install 100 blogs/splogs in this server by this year.
I wonder this server can handle them alone or will need another box.
Thanks!

won't be a problem Heat

There is no such thing as it can support "x" hits per day. Each and every single script is going to require different amount of resources, be it cpu, ram, I/O which means it's not even plausible to begin to predict.

The number of entries in each blog along with the plugins will be the deciding factor, for example if you have several blogs with hundreds of thousands of entries they are going to take longer to render and more processing power to render than a few blogs with 1-2 entries each are.

All in all you have done what you can with regards to the super-cache plugin and should be able to run what you want (around 100 blogs) providing they are small to mid-size. As 200 uniques is not alot per day.

If you say those 200 uniques per day turn into 1000 page views and then you have 100 blogs that's, 100,000 page views a day to split up which works out at less than 2 requests per second which that system can easily handle without any difficulity at all.

One last thing to add, you should go to centos 5.2, no point deploying systems with older operating systems.

Thank you Scott. much helped :)

Using a cache plugin for WP will get you a long way as well in reducing load, but I am certainly not an expert in that area!
