linux - Cygwin 32 faster than Cygwin 64? High grep memory usage -

-

i grepping large files. when run command on cygwin32, completed in 46 seconds. however, when run same command on cygwin64, memory use climbs , memory exhausted after 30-40 minutes.

shouldn't cygwin64 faster cygwin32?

here's couple things tried:

  • avoid caching fresh file names
  • reinstalling cygwin64 new mirror site (to avoid incomplete package)

i upgrade cygwin64 work updated split command options. however, need grep work too.

please let me know if have idea of what's going on.
