Errol are is "test3" host proxying RTP audio stream? You can check is by command tcpdump -ni ens192 udp and port not 5060 If stream exist you will see one output string per one RTP packet On Mon, Apr 6, 2015 at 8:22 PM, Errol Samuels <ewsamuels@gmail.com> wrote:
Hi Stanislav,
Just to let you know I have a customer using all 3 virtualization technologies mentioned (KVM, Xen and VMWare) and they all seem to be happy. However for the larger setups with 2500+ users my preference is KVM without a doubt. I have for example an install with 4 FusionPBX / Freeswitch VMs with Kamailio in Front for residential phone service all sharing same Postgres DB and serving 5000 users, 4000 DIDs running for more than a year with no voice quality issues. We using Proxmox for this setup and it works great.
Test 3 ====== This one is using Proxmox and -t20 with some strange results!?

This is interesting if not alarming..lol
I re-ran the test on DO again below but with -t20 this time now the latency seems to be ~9ms.

A customer is setting up a new telephony switch, and I'm helping them to organize the testing. I noticed the slipping frames in received audio, and then at first I though it's the failure at the receiving side, but then figured out it's my host at DO that is generating unaligned RTP flow.
So, now I'm trying to figure out what would be the best virtualized environment to run FreeSWITCH :)

I'm thinking to move my test server (the one on receiving side) from Xen VM to a physical ARM machine at https://www.scaleway.com/ in France. It would record audio and raw UDP packets and provide them for downloading to everyone.
Do we know about any timing issues on ARM platform?
if someone sponsors some additional DID numbers, that will be appreciated.

Depending on the host and guest OS the timing will be a product of several thing. If some of the features FS tries to detect are emulated, it can be a problem.
The primary thing FS looks for is a kernel with timerfd support. This should be the most accurate. If the guest OS supports timerfd but its using emulated hardware, it might not work as well as it should.
So on something like openvz, you might have support for timerfd in your debian 7/8 instance but the host kernel has no support at all. So in theory kvm would be preferred since it actually boots the guest kernel and you have a chance for it to hit the real timer hardware.
If no timerfd is present, it reverts to the single thread ms precision thread with conditional broadcast for timing. You can also manually configure a combo of one timerfd timer and shared broadcast.
This param in switch.conf.xml helps to tune a few behavior you might want to compare results on.
enable-softtimer-timerfd
true|fd-per-timer --- Use one fd for each timer instance (default)
false --- Don't use timerfd at all
broadcast --- Use one timerfd and share it with conditional broadcasts
This is one reason we do not support virtualization as its too variable to provide definitive policies to make things work every time.
