Well.... Because I sell them, doing proper tests and benchmarks is something I've done a lot of... A 500Mhz Geode system sucking a massive 5 watts can handle 85 concurrent VoIP calls at a rate of 10 a second, and still have processing power left over to run the web/apache/php GUI thing..... (And it does it in what's effectively 128 MB of RAM too) Your 1.5 GHz laptop ought to be able to do about 250 concurrent calls (My 1GHz VIAs stop at about 200). The limit becomes kernel efficiency in terms of context switching and it's ability to handle data to/from external sources via the PCI bus. (Each VoIP channel runs at 50 packets per second each way - those pps soon mount up!) Hm. I have an old old laptop that runs at 200Mhz - one day when I'm bored I might just run asterisk up on it. Oddly enough it too has a broken screen! Gordon -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
