According to the marketing blurb, "The benchmark was a standard SIPP test and was performed by SGI and Signate. The results compared similarly configured systems: an Altix 350 with dual Intel® 1.5GHz Itanium 2 processors/400MHz front side bus/2GB memory compared to a dual 3.0GHz Pentium 4 processors/800MHz front side bus/2GB memory. The results based on simultaneous calls terminating with comparable voice quality were 5,002 for the Altix 350 versus 333 for the PC." Its interesting how marketing people leave out the details. The statement only addresses terminating calls (which one is left with the assumption the test only addressed call setup, not teardown, cdr, etc), doesn't mention whether any of those calls could actually carry on a conversation, hints that no other application (eg, voicemail) was in use simultanously, and most likely assumes the equivalent of canreinvite=yes on a local lan segment following call setup. However, the stats do seem to support what many of us have already experienced, and that is the pci bus limitations with some Intel chipsets is far less then reasonable for realtime apps (such as *). It would be very interesting to see some real life stats with a reasonable mix of * apps including voicemail, transcoding, T1s, etc. "If" the box could actually sustain 5,000 real life simultanous calls, it could replace a hugh percentage of the US class-5 Central Offices (not to mention PBXs). ;) _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
