I have a nice toy to play with: Dell R920 with 60 cores and 1TB ram [1].
The context is the current machine in use by the customer is a 32 core one, and due to growth we are looking at something larger (hence 60 cores).
Some initial tests show similar pgbench read only performance to what Robert found here http://rhaas.blogspot.co.nz/2012/04/did-i-say-32-cores-how-about-64.html (actually a bit quicker around 400000 tps).
However doing a mixed read-write workload is getting results the same or only marginally quicker than the 32 core machine - particularly at higher number of clients (e.g 200 - 500). I have yet to break out the perf toolset, but I'm wondering if any folk has compared 32 and 60 (or 64) core read write pgbench performance?
