As with almost any performance work, your mileage may vary (in particular the 64-bit JIT may work differently) and you almost certainly shouldn’t care. Relatively few people write production code which is worth micro-optimizing. Please don’t take this post as an invitation to make code more complicated for the sake of irrelevant and possibly mythical performance changes. It took me a surprisingly long time to find the problem described in the previous blog post, and almost no time at all to fix it. I understood why it was happening. This next problem took a while to identify at all, but … Continue reading Optimization and generics, part 2: lambda expressions and reference types

Relatively few people write production code which is worth micro-optimizing. Please don’t take this post as an invitation to make code more complicated for the sake of irrelevant and possibly mythical performance changes. I’ve been doing quite a bit of work on Noda Time recently – and have started getting my head round all the work that James Keesey has put into the parsing/formatting. I’ve been reworking it so that we can do everything without throwing … Continue reading Optimization and generics, part 1: the new() constraint (updated: now with CLR v2 results)
