Seconded. Performance is the main thing holding me back.<p>I&#x27;m very excited about C# and other .NET languages for server applications, and would like to make it my primary server side environment, but am waiting for three things:<p>1) A production ready compiler and runtime on Linux (coming) 
2) Tooling to support the new .NET project structures and dependency management (coming, it seems) 
3) A production ready server solution with reasonable performance. On Mono, .NET Linux server apps consistently score near the bottom of benchmarks, essentially ruling it out.  (Who knows? It seems too early to know whether this will happen.)
