Yes, the figures are tps for a 300 second run.
It is for select-only transactions.

What does "Thrds" denote?
It denotes number of threads (-j in pgbench run)

I have used below statements to take data
./pgbench -c 64 -j 64 -T 300 -S  postgres
./pgbench -c 128 -j 128 -T 300 -S  postgres

The reason for posting the numbers for 64/128 threads is because we have
mainly concurrency bottleneck when the number of connections are higher
than CPU cores and I am using 16 cores, 64 hardware threads m/c.
