Re: NetBSD 9.0 vs 8.0 network slow


is there any chance to debug and fix msix problem or even bring it
back to msi?

It seems bge interface on 9.0 have only difference with 8.0 by having
msix vs msi and it is making Dell R220 servers totally unusable with
9.0 because sometimes it takes seconds for a packet to leave interface.

Another possible issue is a switch from single interrupt to multiple msi
(and bugs in that area). If you check your -8 and -9 dmesg you should see
details printed about interrupts routed to the bge interfaces (not sure
if you need to boot -v for that nowadays).

There is no any difference except 8.1 find pic msi1 but 9.0 find pic msix1 here:

[     1.033124] allocated pic msix1 type edge pin 0 level 6 to cpu0 slot 17 idt entry 99

all other information is letter for letter. In a case of missing something
I've placed all output here:
