I have been having aproblem with my site being slow and I thought it was my hosts webserver. Here is what he emailed me

Unfortunately you're the one causing this.
Here's output from top showing some of your PHP threads gobbling down over a gig of RAM, and bringing the load average to up over 60.
top - 01:41:32 up 54 days, 7:35, 3 users, load average: 59.75, 59.32, 61.17

Those threads alone total 1094 megabytes, and that's just a sampling of what's running.
Maybe this ties into the long loading times on your site? Your site may have some sort of serious bug.
All told, your PHP scripts were taking 3.5 gigabytes of RAM =\
This is something I don't understand so maybe someone can give me some advice.
