GC / Garbage Collector Make a Aplication Running Slow

[lutfibintoro]

Intensive I/O in memory makes GC work harder and degrades performance. I hope C# builds new features about strict memory hygiene rules and adds manual memory cleanup like delete in C. I believe this small change will make C# applications run faster. But since manual memory management is risky, we make GC still able to do its job.
