Hi all,
I did a quick protocol performance comparison using fio_ceph_messenger
engine having `37c70bd1a75f ("Merge pull request #28099 from
tchaikov/wip-blobhash")`
as a master. I use default fio job and config:
src/test/fio/ceph-messenger.fio
iodepth=128
src/test/fio/ceph-messenger.conf
[global]
ms_type=async+posix
ms_crc_data=false
ms_crc_header=false
ms_dispatch_throttle_bytes=0
debug_ms=0/0
Results:
protocol v1:
4k IOPS=116k, BW=454MiB/s, Lat=1100.75usec
8k IOPS=104k, BW=816MiB/s, Lat=1224.83usec
16k IOPS=93.7k, BW=1463MiB/s, Lat=1366.15usec
32k IOPS=81.5k, BW=2548MiB/s, Lat=1568.80usec
64k IOPS=69.8k, BW=4366MiB/s, Lat=1831.76usec
128k IOPS=47.8k, BW=5973MiB/s, Lat=2677.71usec
256k IOPS=23.7k, BW=5917MiB/s, Lat=5406.42usec
512k IOPS=11.8k, BW=5912MiB/s, Lat=10823.24usec
1m IOPS=5792, BW=5793MiB/s, Lat=22092.82usec
protocol v2:
4k IOPS=95.5k, BW=373MiB/s, Lat=1340.09usec
8k IOPS=85.3k, BW=666MiB/s, Lat=1499.54usec
16k IOPS=75.8k, BW=1184MiB/s, Lat=1688.65usec
32k IOPS=61.6k, BW=1924MiB/s, Lat=2078.29usec
64k IOPS=53.6k, BW=3349MiB/s, Lat=2388.17usec
128k IOPS=32.5k, BW=4059MiB/s, Lat=3940.99usec
256k IOPS=17.5k, BW=4376MiB/s, Lat=7310.90usec
512k IOPS=8718, BW=4359MiB/s, Lat=14679.53usec
1m IOPS=3785, BW=3785MiB/s, Lat=33811.59usec
IOPS percentage change:
v1 v2 % change
4k IOPS=116k IOPS=95.5k -17%
8k IOPS=104k IOPS=85.3k -17%
16k IOPS=93.7k IOPS=75.8k -19%
32k IOPS=81.5k IOPS=61.6k -24%
64k IOPS=69.8k IOPS=53.6k -23%
128k IOPS=47.8k IOPS=32.5k -32%
256k IOPS=23.7k IOPS=17.5k -26%
512k IOPS=11.8k IOPS=8718 -25%
1m IOPS=5792 IOPS=3785 -35%
Is that expected? Does anyone have similar numbers?
PS. Am I mistaken or 'ms_msgr2_encrypt_messages' and
'ms_msgr2_sign_messages' options are not used at all?
