That's the problem we had with Asterisk and HT on a 2.4 Kernel: whenever Asterisk was staying in the RTP stream, and HT was enabled (on a Dell Dual Xeon system), we had choppy audio. After disabling HT, everything was fine again. Nothing measurable, indeed, but you could definitely hear it. So there *must* be something.

Linux doesn't realise that scheduling a process onto one virtual CPU reduces the performance available on the other. There can be some quite bizarre scheduling decisions made as a result that can slow things down. On the other hand, for some tasks, it might not cause problems and thus you'll get a boost. As ever, the answer is to benchmark your configuration with and without HT to see. There's no simple answer. ___________________________________________________ Ticinocom SA - Via Stazione 5 - 6600 Muralto Tel 0844 007070 - Fax 0844 007071 http://www.ticinocom.com _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
