As part of moving from a RELENG8 based image to a RELENG9 or 10, I was
doing some simple performance testing and found RELENG_9 to be quite a
bit faster when generating traffic through a pcengines APU (dual core,
AMD64, 2G of RAM). Both are using generic kernels
blasting across an aes-128cbc tunnel, on releng9 I get
# dd if=/dev/zero | nc 10.3.24.25 500
326002688 bytes transferred in 37.188139 secs (8766308 bytes/sec)
vs
# dd if=/dev/zero | nc 10.3.24.25 500
146982400 bytes transferred in 27.750440 secs (5296579 bytes/sec)
on releng10.
Both have identical pf rules, but disabling pf does not make much of a
difference in speed.
I havent started checking any of the default tunables. The box will be
functioning as a VPN router and I was hoping to get at least 50Mb/s out
of it, and I can do that on RELENG9, but not 10.
Any ideas what to do with RELENG10 to get comparable performance out of it ?
