TSO takes no effect on redis? #756

Closed hailongeric closed 9 months ago

hailongeric commented 1 year ago

I configured tso=1 in f-stack.conf, but it doesn't seem to have any effect on Redis. I tested Redis with both tso=1 and tso=0 (package size is 1520), but the performance was the same. I'm not sure what the issue is. Have you encountered this problem before?

I not use tso in Redis, may be you can try testing different packet sizes.
