Hi, I recently bought a XPON SFP unit to use with my RB5009. It works well at 1G but at 2.5G I am seeing a lot of tx queue drops. SFP’s interface becomes inaccessible some times.
I found a few old threads here and it looks like this has not been fully fixed.
Is there any thing else I can try to improve this?

Previous similar threads here:
This problem is not specific to the SFP interface or the SFP module.
I have TX Queue drops on all interfaces. I am running 7.13.1 on this rb5009.

I see a couple of threads like this http://forum.mikrotik.com/t/crs-ethernet-tx-drops/136924/1 with similar problems on CHR and no clear solution.
using mq-pfifo on the interfaces instead of only-hardware-queue fixes this problem.
