| sapd1 | Hi johnsom , I would like to custom number of process in haproxy in amphora. But I can't find any haproxy template in source code. Please give me. :D | 02:38 |
|---|---|---|
| johnsom | sapd1: multi process haproxy breaks the active standby ha capability | 02:41 |
| sapd1 | johnsom: I don't know why? | 02:42 |
| johnsom | The templates are under octavia/common | 02:42 |
| johnsom | sapd1: yes, all of the session sync breaks with proc more than 1. | 02:42 |
| sapd1 | johnsom: I thought in amphorae backend. | 02:43 |
| sapd1 | I got it./ | 02:43 |
| johnsom | sapd1: bionic with haproxy 1.8 should allow us to start scaling with the cpus | 02:43 |
| sapd1 | johnsom: I'm trying to build amphora image with haproxy 1.8 | 02:43 |
| johnsom | So, coming with stein release | 02:43 |
| sapd1 | Because when benchmark amphora I just got 10k concurrent request per second but just consume 20% CPU | 02:45 |
| johnsom | Yeah, I can get 30k with 1vcpu amphora | 02:45 |
| johnsom | Proc setting in haproxy won’t help 20% utilization | 02:46 |
| sapd1 | johnsom: Do you have special config or tuning for amphora? | 02:47 |
| johnsom | sapd1: I have some enhancement I will post soon for stein. | 02:47 |
| johnsom | sapd1: a big one is http reuse safe | 02:47 |
| johnsom | sapd1: allows backend connection reuse | 02:48 |
| johnsom | Assuming you mean http protocol. With TCP I got 14gbps out of an 1vcpu amp | 02:49 |
| sapd1 | are you using Linuxbridge? because Bandwidth of my instance just got 8Gbps. | 02:50 |
| sapd1 | with bonding two 10Gbps NIC | 02:50 |
| johnsom | Yeah, linux bridge all local, so no under cloud performance issue | 02:50 |
| johnsom | Under cloud networking is a whole different issue | 02:51 |
| johnsom | Nics, jumbo frames, switch config, etc | 02:51 |
| johnsom | Though I think ovs is faster than linux bridge, more so with dpdk | 02:52 |
| sapd1 | johnsom: I'm using SR-IOV for VIP Network | 02:52 |
| johnsom | sapd1: do you really have an application that needs it, or just doing benchmarking? | 02:53 |
| sapd1 | johnsom: just doing, Because I'm working for Public Cloud provider. So I need benchmark when release a product. | 02:53 |
| johnsom | Yeah, 8gbps on a 10gbps nic is reasonable. Bonded is per stream, so, not true 20 | 02:54 |
| johnsom | Yeah, I looked at this recently for a marketing team too | 02:54 |
| sapd1 | johnsom: BW is not a problem. I would like to higher connection rate :D | 02:58 |
| johnsom | Yeah, I could get 30k. We need more work on optimization and maybe active/active to go more. Plus 1.8 and threads. | 02:59 |
| sapd1 | johnsom: I tested UDP on 3.0 RC release recently. | 03:04 |
| sapd1 | johnsom: How plan about active/active? Maybe on Stein release or T release. :D | 03:04 |
| johnsom | Yeah, UDP did pretty good for me | 03:05 |
| johnsom | Sigh, I really want to focus and finish act/act but keep getting distractions | 03:05 |
