Hello,<BR>
<BR>
I have Asterisk running on Solaris 10 on both Sparc and AMD. The performance of the system is greater on Solaris compared with Linux, due to many factors. The most gains are received when using mtmalloc library. Here's a link to a report I've done. However, do keep in mind that the numbers mean nothing about _real_ call concurrency amounts, but rather serve to show the difference in performance of the two operating systems. However, the numbers do show that you can do more on Solaris than Linux. The actual real world number of concurrent calls is totally dependent on what the VoIP operator is trying to accomplish (ie: echo cancel, codecs, transcoding, etc.) The biggest downside to Solaris is the lack of a kernel driver for Zaptel hardware. However; this is something I'd like to work on.<BR>

I'm curious if anyone is running Asterisk on Sun Fire T2000 or similar UltraSPARC T1 servers.<BR>
Or maybe generally running Asterisk over Sparc in production environment.<BR>
<BR>
<BR>
Anyone? Any comments about performance using Sparc?<BR>

Can you share your expectations how many G729 transcodings can be done
on dual dual-core Opterons or P4 with 4 Gb of memory on SIP-to-SIP
environments ( no TDM or echocancelers involved)
My guess is about 250-300 simultaneous calls.

I don't have any first-hand experience, as we don't do performance benchmarking like that.
In any case, the amount of memory will make no difference at all. The clock speed of the CPUs and the speed of the memory bus will be the determining factors, so realistically I would expect the Opterons to perform better than P4s due to their much more efficient memory subsystem.
However, I can say that I doubt any existing PC-type platform will be able to achieve 250 or 300 simultaneous G.729 transcodes; any single box that could handle that would cost far more than a pair of lower-performance systems to do the same thing (think scaling horizontally, not vertically). In addition, when Digium releases the hardware G.729 transcoder board in the near future this will become less of an issue for deployments of that size.
