Hardware and Performance / Re: Poor Throughput (Even On Same Network Segment)
« on: October 22, 2020, 04:06:09 pm »Be honest to yourself, would you buy a piece of hardware with only 2 cores if you have to requirement for 10G? The smallest hardware with 10 interfaces has 4 core minimum.I think we may be talking past each other here. I'm not talking about purchasing hardware. I'm discussing a lack of throughput that now exists after an upgrade on hardware that performs at a much higher rate with just a software change. That's why we're running tests on multiple VMs, all with the same specs. There's obviously some bottleneck occurring here that isn't just explained away by core count (or lack thereof).
I have customers pushing 6Gbit over vmxnet driver.I'm more interested in trying to understand what is different in my environment that is causing these issues on VMs? Is this claimed 6Gbit going through a virtualized OPNsense install?. Do you have any additional details that we can check? I've even tried to change CPU core assignment (change number of sockets to 1, and add cores) to see if there was some weird NUMA scaling issue impacting OPNsense. So far everything I have tried to do has had no impact on throughput, even switching to the beta netmap kernel that is supposed to resolve some of this did not seem to work yet?
