Not based on information so far. Unless the problem is platform or architecture dependent, which would surprise me, it's likely a problem local to your machine. I cannot reproduce it on WinXP x86. You could try running 'strace' on it and look at the numbers on the left to see where the big jump happens. That would at least give you some insight into what call is taking the time. BTW, I'm not suggesting you send the 'strace' output to the list. Just if you want to see if there's something there that supports your findings so far and what may be involved. My WAG would be . I'd also recommend that any future problem report that you make follow the guidelines found here: . -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
