🧰 multithread-io

Multithread I/O simulation on Windows API.
Mainly focus on testing multithread & overlapped I/O on various enviornment (number of files, file size, compute time...)

All test result and analyze is located at wiki page

Profiling code is inserted with Concurrency Visualizer SDK.

On Debug build, you must install Concurrency Visualizer Extension, and add SDK to project.
On Release build, you don't have to install and include it.

Test Coverage

1. Performance Evaluation

   • Overlapped IO Performance
   • Read Call Task Overhead

2. Compare Thread / Task Scheduling

   • Multithread Sync vs Overlapped IO
   • Overlapped IO
     • Do Read Call Task as soon as possible
     • Role Speficied Thread
   • Memory Mapped File

3. Stress test

   • Massive File Count
