The OS is WinXP SP3.

Since latest round of Windows patches, the path completion has been slowed down significantly (may take a second or two for the prompt to come back).

The patches applied are

KB980373
KB981716/MSACCESS
KB981716/ACCWIZ

Anyone has any idea/suggestion to fix the performance issue?

The problem is bash-completion, unfortunately. I recently installed bash-completion on a cygwin 1.7.7 system (Win7x64) and bash startup time went from 1 second to 35 seconds. Using Sysinternals Process Monitor I can see bash-completion doing a scan of just about every potentially executable file (at least open/close) in the Windows directory and Program Files. The only solution is to disable it or uninstall it; this page provides more information
