    @Panda You should be able to use {% javscript %} as shown in this video - it’s quite the watch, but very educational, and provides insight as to how this works - see below screenshot for an example

    @crazycells hi - no security reason, or anything specific in this case. However, the nginx.conf I posted was from my Dev environment which uses this port as a way of not interfering with production.

    And yes, I use clustering on this site with three instances.

    Seems to be better with some scaling fix for redis on redis.conf. I haven’t seen the message yet since the changes I made

    # I increase it to the value of /proc/sys/net/core/somaxconn tcp-backlog 4096 # I'm uncommenting because it can slow down Redis. Uncommented by default !!!!!!!!!!!!!!!!!!! #save 900 1 #save 300 10 #save 60 10000

    If you have other Redis optimizations. I take all your advice
