Balance all subscribers between CPU cores

We have multiple channels. Some of them have from 500 to 1000 subscribers, others have many less.
Thus some subscribers of highloaded channels suffer from delays.
I wonder whether there are some way to balance CPU capabilities not only between channels, but between subscribers to have equal number of subscribers distributed among each CPU?

Maybe there's some kind of configuration to speed up delivery?

Thanks!

Hi @yaroslav-phokus inside the module we don't have control of in which process the user was connected to, this is something lower level.
On top of my knowledge, what you can try to improve is the affinity between the Nginx processes and the cores, and then the distribution of connections per process, something like the accept_mutex
These should improve the distribution optimizing the deliver.
