To ngen or not to ngen?

[PSiegmann]

Hello,
we have a small application on one server that does every 10 minutes
(cronjob) some filetasks and very basic SQL queries against an
installed SQL Server Express instance there.

Does it make sense to ngen that application?

No, ngen is not intended for server type applications. In fact, the ASP.NET
engine will simply ignore the ngen image and revert back to the original
image. It won't tell you so, so you might think it is working but it really
isn't (something to do with shared assemblies, but it isn't really
important). You should be simply using the site warmer feature of ASP.NET to
keep the application warm.

It's not an ASP.NET application. It's a command line app, that gets
executed every 10 minutes.

If this is a console app, you can ngen. I saw server in your post and
immediately assumed server application. Sorry.

If you're doing the same thing over and over again, NGEN will only make the
first invocation of the application quicker. The JIT compiles code as it
runs, once it runs it keeps that compiled code around to be reused for the
next time you run the application.
