Slow site? ASP.NET application keeps restarting?

[Bosh]

My site doesn't always get a visitor every 20 minutes, and, as a
result, my visitors must sometimes endure the slow restart process. I
tried various recommended solutions, such as Paul Wilson's
WilsonWebCompile.dll, but none of them solved the problem. Eventually,
I stumbled across a Web page monitoring program, and that did the
trick. After months of testing, I'm here to say that Web page monitors
are a reliable solution. I've evaluated quite a few, including C4U
Scout, Check4Me, Check4New, Karen's 'Net Monitor, Site Snitch, and
WebMon, all of which are freeware. 'Net Monitor is my favorite because
it has the lowest memory and CPU usage, with Check4Me coming in 2nd
place. Site Snitch is cool because it can follow links up to 3 levels
deep, but it's a bit of a resource hog.
