Can one line of code in C# JIT compile into two different blocks of code in the same program? This sounds a little tricky but in fact is very easy and happens pretty often. Consider the following code: Now let’s see the loop in the machine code: You can see that C:\Users\user\Reordering\Program.cs @ 9: appears … Continue reading Reordered code after compilation
This is the seventh part of the Custom memory allocation series. For your convenience you can find other parts in the table of contents in Part 1 — Allocating object on a stack We know how to allocate object on a stack, however, we did this in .NET Framework. Can we do the same in … Continue reading Custom memory allocation in C# Part 7 — Stack allocation once again
This is the sixth part of the Concurrency series. For your convenience you can find other parts in the table of contents in Part 1 – Mutex performance in .NET Let’s start with the following code: We want to acquire a mutex. Since the operation might fail, we want to log the timeout, handle the … Continue reading Concurrency Part 6 – Abandoned mutex
This is the fifth part of the Concurrency series. For your convenience you can find other parts in the table of contents in Part 1 – Mutex performance in .NET Last time we called WinAPI through P/Invoke, today we are going to call it directly. Code Results The results are: As you can … Continue reading Concurrency Part 5 – WinAPI mutex
This is the fourth part of the Concurrency series. For your convenience you can find other parts in the table of contents in Part 1 – Mutex performance in .NET We have already seen a mutex in C# but last time it happened that Java JNI is faster. Let’s compare it with P/Invoke. Code As … Continue reading Concurrency Part 4 – .NET with P/Invoke
