LINQ in a new application domain (AppDomain)

Question

Google Workspace

Does anyone have any idea why JIT compilation of the same LINQ query takes 4 times longer in the new domain (child AppDomain) than in the main (default AppDomain)?

Answer 1

Could you send an example of your code?
I conducted such an experiment ( here is just the code ).
Launched the program twice. Once called a loop with the creation of a class instance in the usual way.
The second time is by loading from an external assembly and running in a new domain.
The results are:
Hamster: 50000
Domain hamster: 00:00:00, Hamster: 00:00:23.5093447
Domain hamster: 50000
Domain hamster: 00:00:26.9815433, Hamster: 00:00:00.0010000
That is 00:00:23.5093447 and 00:00:26.9815433. For a loop of 50,000 repetitions, the difference is about 3 seconds. Of course there is a difference, but not 4 times, and even with such a number of repetitions, most likely the numbers would differ much more?
Perhaps you have a more complex linq query? It has become very interesting to understand.
