Ok, I got Your point . Talking about array size its somehow fixed at 136 , I havent found a place to change that yet . Going back to scalability , how do You expain such case:

When I separatelly run pmdtm binary I can easy scale to number of that execs x 30k rows per sec each .
But when doing that 'inside' one pmdtm via parallel threads I can go for: 2x 30k rows per sec for parallel = 2
but only
4x 15k for parallel = 4

so its not scalling well even when Im quering different partitions . But still not sure why I cant saturate 100Mbit eth with one net8 session . Regards
