I have Dedi Server in Hetzner (Germany)
And those are my statistics :
Can you please tell me why I see so huge amount of cache misses ?
Thanks again in advance for your help and wish you Happy New Year...
Is Self managed, my Community is https://xiaomi-miui.gr & https://xiaomi-miui.gr/community (Forums)

It will be nice to help me correct any config mistakes I have, because as we are over https, I think some extra config needed to maximize the benefits of MemCached & pagespeed modules.
Here are also the memcached stats....
