Re: Bash / cygwin process spawning (?) performance very slow

I took the plunge and spent almost a full day trying to find the cause.

1. Booting into Safe Mode gave a huge performance boost
2. By eliminating all services and programs in Normal Mode, one-by-one, I found the offender:

turns out that Comodo Firewall (Free version) loads a DLL in each process that is the cause of the delay.
Although I only use the Firewall, and do not use any "AntiVirus" features, still it causes delay during startup of a process.

However, after disabling it -- which did speed up process spawning in Bash --  I encountered the other problem I already had much more often.
For now I consider the issue of slow spawning to be solved
(although it would have been nice if there was an easier way to diagnose it, maybe with tracing?)

Regards,
Paul
