Throttling Compression Operation? about easycompressor HOT 1 CLOSED

Hi, first I recommend using other algorithms such as LZ4 or Brotli if it's possible for you because LZMA itself or maybe the current implementation (LZMA-SDK package) that EasyCompressor uses is not so efficient (both in CPU usage and Memory usage).

Just so you know, if you decide to use Brotli make sure to use the .NET built-in Brotli implementation which is included in EasyCompressor package (not the EasyCompressor.BrotliNET).

Also, make sure to use CompressionLevel.Optimal (that is by default in EasyCompressor) because the CompressionLevel.SmallestSize takes too long to process and is not cost-effective.

By the way, there is no way to throttle only a method in .NET to limit CPU or Memory usage.

But If you use orchestrators like Kubernetes or Cloud-based infrastructures you can limit your CPU Cores.

You can also limit your Entire Process through Windows by setting Process Priority to Low and Process Affinity to Minimum CPU Cores (like this or by third-party apps)

However, I think can't limit your Memory usage because if you don't have enough memory you will run into OutOfMemoryException

You can do the same using C# by setting Priority and Affinity of your Current Process or ProcessThread like this:

Process currentProcess = Process.GetCurrentProcess();

currentProcess.PriorityClass = ProcessPriorityClass.Idle; //Low

int affinityHex = 0x0002; // use only the second processor, despite availability
//affinityHex = 0x000F; // use only any of the first 4 available processors

currentProcess.ProcessorAffinity = affinityHex;

//ProcessThread processThread = currentProcess.Threads[0];
//processThread.PriorityLevel = ThreadPriorityLevel.Idle;
//processThread.ProcessorAffinity = affinityHex;

Note: The value of affinity is hex-base and you must calculate it based on which CPU Core/s you want to be available for this process. (more info and here)
