Recently at a team meeting, one of the guys who manages our server mentioned how a Wordpress site that we're hosting as part of a company wide initiative is consuming 30% of the server's memory.
I'm trying to figure out why.
When I run a copy of the same site on my local box, I get this:

Google Chrome is the browser that is running the WP site.
Is 243 MB a lot? Is that enough to consume 30% of our server's capacity.
I want to give him either some context or direction - perhaps both. There's not a lot of traffic to the site, and certainly not a lot of interaction with the database. I just can't figure out why this is such a burden.
Then again, perhaps the answer is staring me right in the face, as far as 243 MB.
Is that a lot? Are WP sites generally hard on servers? Is there a way to make it not so taxing?
What do you think?
My coworker has to go to our Systems Dept and ask for this site to be moved. Before we do that, though, I want to get some context. Is 243 MB representative of a significant burden?
Basically, what I hear you saying is that when I look at my "Task Manager," I'm not getting a look at what my site is consuming according to my local computer which is not at all the same thing as a server. So, any attempt to diagnose the site using that approach is going to be pointless.
I am going to assume that between the galleries and some of the other plugins, what may have appeared incremental at the beginning has become a bit of a "gas hog" since then and moving the site to a different server will most likely be the best option.
Thanks for the insight!
