The FAQ entry does not mention performance, but real failures. >> How to further diagnose this? 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?)
