Configure input multi-core processing. Read more in Routing Protocol Multi-core Support article.
alone - input and output of each session are processed in its own process, most likely the best option when there are a lot of cores and a lot of peers
afi, instance, vrf, remote-as - try to run input/output of new session in process with similar parameters
main - run input/output in the main process (could potentially increase performance on single-core even possibly on multi-core devices with a small amount of cores)
input - run output in the same process as input (can be set only for output affinity)
You are correct. After a reboot it no longer taps out one core. Mikrotik needs to figure out how to optimize Winbox so something as simple as ip/route or ipv6/route does not cause such behavior even after the ip/route box is closed or the Winbox session has been closed.I saw that I have this issue once I open ip/route or ipv6/route windows on winbox.
If I reboot the router and don't open those windows, I don't have any core at ~100% for routing
In my case I closed all windows and waited an hour as well as exited the Winbox session and opened a new one with only the system resources cpu box open and it was still tapping out a core. This was replicated on 4 x86 7.8 routers as well as a 7.8 CCR2116sometimes when you open winbox and a window with many elements that consume alot of resources
is a matter of clossing that windows and then exit winbox
reopen winbox and wait (without opening a window with many elements) some minutes and that 100% core will be gone
windows with many elements:
simple queues when you have a lot of them
ip firewall when you hav a lot of rules
ip firewall connections when you use conn tracking
ip routes when you have a lot of routes
i think they have optimizes this, in some age problem was worst, i hope this improve, several full tables will be a increasingly frequent situation on CCR2216/2116
Im also seeing similar issues, Im currently testing on V7.10rc1Does this happen if you print the table in the terminal directly outside Winbox as well?
