Why it is Loading Slowly..?

hi
When i ran my aspx file it is loading slowly in first time and second time it will wok very fast. It is nice. But When i restart my system angain the page is loading like a first time compile mode. so totally hole my application will be running slowly i think it is recompiling.

any solution..?That is just the compilation pattern of .NET where everything is Just-In-Time (JIT) compiled. It only compiles whatever you need at that time and then commit it in memory. In this sense, its faster...AND it is.
thanks for reply,

But what is the advantage if it is running for JIT..?
One more doubt. If 6 users are using my .aspx file will it be compile for 6 times are one time (first user) has compiled and executing slowly for firs user.?
One time then it stays in memory
