Apologies if this is a duplicate, I never saw it appear on the list.
After installing bash-completion, bash startup goes from about 1/2 second to
10-15 seconds. During this time, the bash process (as viewed in Process
Explorer) consumes almost no CPU time, but the System process (PID 4) is
pegged at 100% on one core. As soon as bash finishes starting up PID4 cpu
time goes to zero. This is highly repeatable on my system:
Win7Pro X64
Intel i7-920
12GB memory
I removed bash-completion and bash startup time went back to the usual 1/2
second.
This is a known upstream issue that's been reported to the list in the past.
The current plan is to adopt the fix when it is released.
