It isn't as slow as yours, but definitely slow.

$ time /c/windows/System32/tasklist.exe /m normaliz.dll | iconv -f CP866
  ...skip...
real    0m0.093s
user    0m0.015s
sys     0m0.030s

$ time /c/windows/SysWOW64/tasklist.exe /m normaliz.dll | iconv -f CP866
  ...skip...
real    0m15.560s
user    0m0.000s
sys     0m0.045s
