Slightly off-topic, as the thread was about an embedded system:

It depends on how many of those one-time delays a website has:
If you bring a big and heavily visited site back online, those
delays are over-significant.

W/out a cluster/reverse proxy/traffic shaper or at least a
spider that pre-compiles the pages before your visitors are back,
your server will have a hard time dealing with a lot of forked
mcs processes.

This is the reason why mcs will be someday extended for in-proc 
compilation and why MS came up with pre-compiled sites.

It's unrelated to JIT compilation as ASP.NET requires classic
source code to assembly compilation.
