Slow Queries / Configuration Help
-
Hi, this this sort of slow “time” graph normal?
I have spent the last few hours looking through these forums to help and possible configurations, but not really finding answers.
My server does not seem to run out of memory or have high CPU usage. I just want to make sure that Redis is working optimally.
Total server memory: 32GB
Redis maxmemory 6GB
maxmemory-policy allkeys-lru-

That’s unusual. It seems that Redis Server is responding rather slowly at times.
Can you post your
Redis-cli INFOoutput?Hey you go @tillkruess. Thanks!

I’d ask your hosting provider for assistance with the slow response times and maybe install a Redis monitor to see what’s going on there.
