I have multiple Wordpress websites on my server(And a game server and Tomcat) and I'm a little paranoid about my servers health. How much does a newly installed Wordpress take typically?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.If this question can be reworded to fit the rules in the help center, please edit the question.

This is impossible to answer because it depends what you are doing with it. – Wyck Aug 30 '13 at 21:29
@Wyck I said CLEAN Wordpress if you didn't read the question – Louie Aug 30 '13 at 21:36
Clean is not a clear definition, what exactly does that mean? Which theme, no plugins, no traffic, which type of server, etc? Also you accepted a horrible answer which is wrong. – Wyck Aug 30 '13 at 22:19
How much world would a WordPress take if a WordPress could take world? – GhostToast Aug 31 '13 at 1:20
No traffic = WordPress doesn't run at all = no 'power' used – shea Aug 31 '13 at 1:53

This type of question is open ended to answer because it depends on many variables. The typical memory usage of bare WP usually starts at 15MB and scales up.

What you can do is turn on debugging and install the Debug Bar plugin and it will show you the amount of memory you're using.

In wp-config.php set define( 'WP_DEBUG', true );

Debug Bar plugin showing memory usage

Another plugin which shows peak memory usage: TPC Memory Usage

A new WP install does not need 15MB allocated for it. – STing Aug 30 '13 at 22:28
I never said it did, I said a "typical" install starts at 15MB, you would be hard pressed to run below 10MB without any caching in place even on a bare install. – Wyck Aug 30 '13 at 22:29
A new install runs at 4MB of memory on my server. Also good link to a plugin not updated since 2.9.... Anyway on what server is 4-15MB going to affect? He asked a simple question and you gave him a complex answer. You do have a picture in your answer that really shows nothing. You didn't mention how to set up indexes right or actually do a clean install and see what the variance is. Anyway I have large WP sites with 1000+ posts/pages and 50K users and they run under 15MB... It is all about the number of queries hitting your DB and if you allow crappy plugins. – STing Aug 31 '13 at 5:52
The plugin update date has nothing to do with anything, it works perfectly fine, your attitude is immature and not going to go very far on this site. – Wyck Aug 31 '13 at 6:22
@SumTingWong you need to sort your attitude out. Stop trolling and start learning how to be courteous. – anu Aug 31 '13 at 10:06
