Baremetal, hyperthreading?
Hello all, We’re having a discussion regarding whether it is better to have hyperthreading enabled or disabled. What’s you take on this? Thanks -- Regards, David Villasmil email: david.villasmil.work@gmail.com phone: +34669448337
The answer is "it depends". HTT/SMT will increase your scheduling latency and cause extra jitter. Plus make "os load" vs "real capacity" very non-linear and hard to depend on for capacity planning purposes. Whether or not that warrants potential 5-15% increase in max throughput depends on your constraints. Measure carefully and proceed with caution. -Max On Wed., Jun. 10, 2020, 7:45 a.m. David Villasmil, < david.villasmil.work@gmail.com> wrote:

Hello Martin, I'll save you some money :) It's not kamailio replying with "500 Overlapping Requests", it's freeSWITCH. It seems to me they're sending the reINVITE WAY too quickly: ACK to 200: Jun 3, 2020 00:35:56.421500000 WEST (re)INVITE: Jun 3, 2020 00:35:56.430197000 WEST [image: Screenshot 2020-06-11 at 11.15.24.png] (10.40.4.21 is UMG's side) As you can see, they're sending the reINVITE about a millisecond after the ACK. I'm not sure what FS says about this, I would have to look at FS' logs. If UMG could hold off that reINVITE for a second I think it would probably solve the problem.
