  Thanks, we welcome you.

  Don't worry, some members can speak English.
  ...but...I cannot speak English well ;)

  That's Great!
  I want to see your patch. Please send me it.

  I want to see your patch before merging to UM-L7 git tree.
  
  Makefile and .spec files are not required, please tell me
  compilation methods instead.
  
  One of the members is a specialist of autotools ;)

  Because we don't have the knowleges of splice() syscall, it has not
  used it yet.
  
  If the performance goes up by using it, I want to examine it again.

  Of course, the SMP system cannot be effectively used with UM-L7 v2.x.
  
  The multi threading version with IPv6 support is implementing
  just now, and scheduled to release it in February 2010.
  
  "ultramonkey-l7-v3" is the skeleton for multi threading version, 
  and it has nothing yet.

  The command/module to display by other formats has not been
  implemented yet.
  
  Certainly, these format is used in a lot of performance
  monitors(e.g.: httperf), I think that it is a useful format. 
  
  I want to examine it in the future. Thank you for the proposal. 
  
  
  regards.
