My b2evolution Version: 2.4

I run a blog that gets about 200 unique visits and about 1000 page views a day... Usually there are 2-3 posts added a day and probably 150-200 comments added per day.

I just recieved the following message from my webhost.

coldheartedtruth.com is experiencing issues because the system RAM is getting exhausted.

Based on your memory usage we strongly urge you to consider upgrading to a dedicated server with at least 2GB of RAM or more.

We would suggest a system such as this, which would give you a lot more RAM, disk space and bandwidth:

Intel Pentium 4 2.8 GHz
2-150GB Hard Drives
2048MB Memory
Centos5
8 ips (5 usable)
1500 GIG Bandwidth
Monthly Price $139.95
Setup Fee $59.95

Right now I have VPS with 768 dedicated RAM to run a blog... which should be more than enough. In fact, before switching to B2Evolution I was able to simply host my site on a shared host for about $15/month.

what could possibly be creating this sort of memory usage? I really like the functionality of B2Evolution, but I cannot afford to run it at that cost, and I cannot believe that it is not designed to handle the limited traffic I get...
