I think it depends on the platform.
Most of the platforms don't have the same situation.
Besides, I think the platform with 100Gbps device may
have faster CPU than that one which I test.

What would happen, if I set the weight to 256 on the platform
which runs well for the weight of 64?
Doesn't it only influence the slow platform?
