And compiling 1.0.1l on RELENG_9 shows the same performance profile on
RELENG_10. Smaller packets are slower, larger are faster
16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes
20245.49k 21646.52k 22179.87k 55431.85k 55981.40k R10
34178.77k 35559.29k 36305.70k 36481.34k 36495.49k R9
20278.40k 21642.28k 22170.71k 56873.98k 57387.69k R9Port
But for my application, I still get better speeds on RELENG_9, even when
using the same version of openssl across RELENGs.
I do the test with the 3 FreeBSD boxes
server1 ---- apu ---- server2
server1 is connected to the apu with openvpn.
I then usr /usr/src/tools/tools/netrate/netblast
to send across the openvpn tunnel to server2
on RELENG9 I get 83-85Mb/s
on RELENG10 61Mb/s
Using polarSSL does not make much of a difference either way. Its
perhaps 1Mb slower on both, so 82-83 vs 83-85 on R9 and 59-60Mbs vs
61-20Mb/s on RELENG10.
But, on RELENG_9, if I install openssl from the ports, and compile
openvpn and link against it, I get 85-87Mb/s of throughput on RELENG_9.
So while there are speed differences between the versions of openssl,
it doesnt seem to matter in the OpenVPN case, as its the base OS that
makes the difference since both versions of OpenSSL on RELENG9 give
similar performance in my openvpn test
On RELENG_9, the dtrace command I use on 10 does not seem to work
0{alix_APU1c4}# dtrace -x stackframes=100 -n 'profile-997 /arg0/ {
@[stack()] = count(); } tick-60s { exit(0); }' -o out.kern_stacks9
dtrace: invalid probe specifier profile-997 /arg0/ { @[stack()] =
count(); } tick-60s { exit(0); }: "/usr/lib/dtrace/regs_x86.d", line 2:
type redeclared: struct devinfo
