Cavium ThunderX Processors used for PostgreSQL?
I was shopping around for a dedicated server and I noticed a plan which
uses 2X Cavium ThunderX processors which gives me a total of 96 cores.
I use PostgreSQL + PgBouncer which accepts many connections at a time. I
have my current one to accept maximum connections of 1000, but it never
goes above 200 active connections but the traffic to the system is always
increasing and I want to have the hardware to handle it.
It's the first time I see the Cavium ThunderX name. How do these compare to
a machine that has 2 × E5-2640 v3? I noticed the Cavium ThunderX is a lot
cheaper, but it's not a known name.
What would I get better results with 2X Cavium ThunderX processors with 96
cores or 2 × E5-2640 v3 with 16 cores?

Probably because it is an ARM processor trying to break into the high
end server market. A search on Cavium ThunderX found a lot of
references. The most recent benchmark I could find was:

depends as much on the storage IO subsystem and workload as it does on
the CPU. does this 96 core system also have the sort of memory
bandwidth to keep up with the core count? how fast are each of those
arm cores compared with the E5-2640v3 cores?
being an ARM, software support will likely lag, and you'll probably
find yourself having to do a lot of your own compiling of stuff beyond
the basic OS.
