I have Magento 18.104.22.168
I was using mirasvit full page cache, now I am using potato full page cache.
My server VDS, 8CPU, 16GB RAM
Now I am using seperated redis servers for 1-sessions and 2-cache+fpc. I also tried via 3 seperated redis server. 1- Sessions 2- Magento Cache 3- Full Page Cache
It is working but after website fully cached, FPC is missing %30 of cached pages. This problem was same at mirasvit. What is the problem? Is this normal as a cache logic? After nearly website fully cached website is going slower.
Second question about Redis cleanup.. Should I use Scheduled Redis cache clean up. I tried to clean via redis-cli.php but I couldnt see any cahnge at key size.
