Thank Peff. Unfortunately I am living with this issue, no one able to find out what is causing this significant delay. Re-initiating this thread if someone can help on this.

If it's happening for just a local checkout operation, I'd suspect very poor filesystem performance. On Linux, I'd run it under "perf" to see where the time is going. Or possibly "strace -T" to time system calls. I don't know what tools are available under HP-UX for that kind of profiling. -Peff
