Hi, in my experience with building yet another DNS resolver from scratch was that the gain from the shared networked cache was heavily paid in the latency. I would encourage you to actually do a performance testing with cold and hot cache and my educated guess is that shared redis cache will he

Re: Bind9 shared cache

2020-04-19 Thread John W. Blue
In BIND views can be configured to share a cache on the same server but I do not think that it can be done between servers. That said, time for a sanity check. Does this configuration resolve a specific technical problem? If so, then I would recommend you keep running your unbound system. If
