| kata-irc-bot1 | <clement> So I double checked and it is indeed more stable than just using runC, however I think the main reason is that by default runC will not use cpuset, while kata containers will isolate the vm on one core | 08:31 |
|---|---|---|
| kata-irc-bot1 | <clement> currently rereunning the benchamrks with runc+cpuset to confirm | 08:32 |

| kata-irc-bot1 | <clement> mmhh, using cpuset makes it slightly better but containers are still more stable :') | 09:57 |
| kata-irc-bot1 | <clement> mmhh, am I misunderstanding https://github.com/firecracker-microvm/firecracker/blob/master/SPECIFICATION.md or does it mean that you to provide a full core to firecracker "for the device emulation thread" on top on the one attributed to the VM ? So to attain the performance they mention I would need one core for the VM and one for firecracker or am I misunderstanding something ? Is it the same for other hypervisors ? | 10:25 |
| kata-irc-bot1 | <clement> I'm trying to know if with a 4phys cores machine, I should run a maximum of 3 kata containers or 4 for maximum stability | 10:26 |

| kata-irc-bot1 | <samuel.ortiz> @clement I think the above specs gives IO performance number for a setup where a core is dedicated to the VM, i.e. nothing else on the system runs on this given core. | 12:07 |
| kata-irc-bot1 | <samuel.ortiz> It does not mean that FC requires a dedicated core. | 12:08 |
| kata-irc-bot1 | <samuel.ortiz> @fandree may be able to give more details about FC device model | 12:09 |
