Jim and all: We are in the process of deploying one of these in our datacenter.
http://www.supermicro.com/products/SuperBlade/datacenterblade/ we are using this blade with dual quad core xeons, 12GB ram and a 640GB RAID5 array. http://www.supermicro.com/products/SuperBlade/module/SBI-7425C-S3.cfm We have the hardware but its going to be another month or so before we have the staff resources to deploy. So if you want 1 blade for each of FreeSwitch, Asterisk and YATE, I can make available but it has to get done in the next month.

Ditner Cc: asterisk@uc.org Subject: Re: [on-asterisk] Conference bridge You know what? That's a fantastic idea! We should set up a basic idea of what we want to test (keep it simple), and the get together and have a 'mix-off' between YATE, FS and Asterisk and see which one can handle the most channels before it starts having issues. We probably wouldn't be able to be too formal in our methodology, so some purists might scoff, but if we did the same sort of test on the same sort of system, it'd at the least give some sort of benchmark as to where the performance differences lie. I would love to test this on the following: - Atom (I have a lab box for that) - Core 2 Duo - Core 2 Quad - Xeon - Dual Xeon Sorting out performance differences between the various projects would be interesting enough, but what would also be neat to discover is whether, say a core2 quad is that much better than a core2 duo, and whether a xeon is far better, or only a little better. I have an intel Atom box that I can bring to the party. Can't currently help with the others, though. Jim Simon P.
