Sorry, don't know why, but its problem with screenshot from vsphere client. Something around 50-300 packets every 30-60 mins.
Before tuning, it was 200-400 every minute.

no not how many drops how many TOTAL packets – ie the ones your not dropping. See my screen shot.

Ah, ok.

Try to see if E1000 network adapter works better for comparison.

So your seeing a LOT of packets!!! Yeah I think adjusting the ring value or ring 2 value might be in order.. But sorry not sure how to do that in freebsd or pfsense.. linux normally just a simple ethtool -G
With intel something with sysctl hw.em.rxd= but not sue with using the vmx3??

Yes, same problem for me. Not sure, can i write just something like hw.vmx.rxd=4096? And which parameter for ring value, and which one for ring 2?…..

Its a little problematic for me. But can be done, if needed. I thought, it will be the same problem.

We saw much better performance from the E1000 than VMXnet2 and 3.
Try it and report back.

Ok, will try later today and will report back.

So, the problem was with receiving buffers. According with https://www.freebsd.org/cgi/man.cgi?query=vmx&sektion=4 i increased buffers of vmx adapters and problem is gone (em works well too, with tuned buffers). After, jumbo frames was overloaded, so i increased this parameter too.
The same with receiving buffers on windows clients, but this is another story…Thanks, guys! :)

Which commands were executed on pfsense?
System: Advanced: System Tunables
hw.em.txd value
hw.em.rxd value
right?System 2 Nics Wan -em1000 and Lan -em1000
