Redis Redis 6.x will have multi-threaded I/O thread for better performance

Redis author posted on twitter that next version of Redis 6.x will have multi threaded I/O thread support for better performance https://twitter.com/antirez/status/1110973404226772995 ! Edit: looks like it's in Redis thread-io branch.

redis 5.0.4 thread-io branch source installed via GCC 7.3.1 threaded benchmarks with --threads 2 for port 6481 redis server

Code (Text):

need to edit redis server port 6481's config file at /etc/redis6481/redis6481.conf add

Code (Text):

io-threads 2

Code (Text):

systemctl restart redis6481

Then test results below

• not seeing performance boost in terms of redis request/sec throughput & latency distribution but only testing on VPS with 2 cpu threads (1 physical and 1 virtual) so not exactly the best server to test multi-threaded redis thread-io branch
