Erm, I'm assuming you mean you don't use the C#/VB.NET compilers and JIT optimizations when you say "optimiser in Visual Studio". And, if that is really true, I think its ludicrous! WTF | :WTF:

Any optimizations you make purely with C#/VB.NET code are at a very high level. You are incapable of making the kinds of optimizations the compiler is no matter how hard you try, because a lot of IL constructs may only BE made by the compiler itself (unless you write IL directly). The JIT makes even lower level optimizations, at the machine-code level, tuned specifically for the operating environment (physical hardware, virtual resource allocations, etc.) within which the code is actually running (and those aspects may change from run-to-run). No matter how much you try to optimize at the code level, you can not foresee each and every operating environment and account for every single optimization, nor are you capable of it.

Optimizing at a high level is only one level of optimization, and it will only take you so far. There are additional levels of optimization that SHOULD be done, but which a developer should not have to worry about (hence the reason we use high-level languages). I think its a load of crap that you don't use the compiler optimizations, and I think its humorous that you actually think your doing a better job than the compiler and JIT by (Laugh | :laugh: ) "saveing every microsocond you can."

Give me a break. Suspicious | :suss: Use the compiler for what it is, a tool to reduce your workload and handle significant, lower-level optimizations for you.
