JITing in C#

Question

Hi friends I want to know that does JITting occur per-assembly or per-method? How does this affect the working set?

Jignesh Trivedi · Answer

hi Per method . Methods that are not called are not compiled thus reducing impact on the working set. The advantage is that it makes the JIT a lot simpler - there's no need to consider old code which is already running undo optimisations based on premises which are no longer valid etc. please refer below link http://research.microsoft.com/apps/pubs/default.aspx?id=121449 hope this help.

JITing is done per method. It increases the working set of the process because once a method has been converted to native code the latter is cached in memory in case the method needs to be called again.
