If you created your swap file following our tutorial you can simply do the following to disable you current swap file:

swapoff /swapfile

Then create a new one using the same procedure. There should not be any need to update your fstab.

If you are seeing a lot of requests and apache is taking a while to respond you may want to check if you have KeepAlive turned on. If you do, this will keep a connection open for a current client. If this is on and your MaxClients setting is too low a new request will wait for one of the kept-alive connections to time out before responding. If this happens you will see slow first response times but actual file transfers and php processing still running normally.
