 Hello mysql,
 
  I've found benchmark for MySQL on Linux with NGPT - the Solaris-like
   pthread compatible threads for Linux, the stable version 1.2.0 of
   which just was released.
 
   The user tested mysql server from binary distribution vs self
   compiled with NGPT.   2.4.19-pre3 kernel was used.
 
   fork_big.pl was used with --loop-cont=5000
 
   MySQL-LinuxThreads
   1 - 0m9.8s
   10 - 1m24s
   20 - 4m21s
   50 -14m47s
 
 
   MySQL-NGPT
   1 - 0m9.5s
   10 - 0m51s
   20 - 1m44s
   50 - 4m29s
   100- 9m50s
 
 
   So NGPT shows almost linear salability winning several times over
   MySQL optimized Linux threads in some cases.

Pjotr, 

have you tested a speed of mutexes and the  availability of adaptive
mutexes ...

Testing can be done with super-smack ...
