While Cygwin is an *emulation* layer, and emulation is inherently slower
than straight execution, there are other potential reasons for the
slowness. Check your anti-virus and firewall software settings. If
possible, exclude the Cygwin filesystem from checking by those tools...
Even little things (like making the tool aware of the often-used Cygwin
programs and telling it to not check "outbound email messages" (!) sent by
those programs) can help speed up Cygwin...
A one-sentence rant: even with those changes, whenever I run a Cygwin
shell script, the stupid vsmon process takes up 100% of the CPU. No known
