Hard to say. Your VPS is short of some resource that it needs.

This could be RAM, CPU power, network speed, disk-IO, a poor choice in 
some set up, or starvation caused by another site on the same host server.

Most likely a shortage of RAM. 250MB is really tiny. If RAM is too 
small, the machine will be paging to disk and bringing the pages back, 
which is very slow.

You can control RAM size (and not much else on a VPS). Try increasing it 
to 500MB.
