Using Ubuntu Server 14.04.1 and Percona XtraDB 5.6.20-68.0-56.
When the cluster is running with all three servers and we do a set of inserts (~800,000 of them) we see
a through put of around 150 inserts/second.
If I shut down servers two and three and now run the same transactions we see a through put of 6,000
to 12,000 inserts/second. It jumps around a bit.
It just seems wrong for the cluster to be that much slower. My my.cnf from the first server is below.
All three servers are the same, Intel Xeon E3-1270 @ 3.5Ghz, 32 Gb memory, and a single 256
Samsung SSD, dual gigabit nics bonded in balance-rr mode and all on the same gigabit switch.
Any thoughts are deeply appreciated
