   That timing is from the current compiler. The more streamlined one I'm   
   working on now (where the IL plays a smaller role) can manage 16Hz; 14%   
   faster.   
      
   There are a few sluggish areas I want to look at.   
      
   And yes it is more of a sport now than a real need.   
      
   My compilers ought to be slow as they have so many passes. Tcc   
   supposedly has only one. So another project I might have a go at is a   
   single-pass C compiler that is faster than Tcc.   
      
   Just to see how fast I can go at producing native code. However, if the   
   code is too poor, there will be lots of it, and it will slow down the   
   latter stages. I'll have to see.
