Any possibility the standby is built with assertions turned out?
That's often the cause of this type of difference between pgbench
results on two systems, which easy to introduce when everyone is
building from source. You should try this on both systems:
psql -c "show debug_assertions"
Or even:
pg_config --configure
on both systems might be worth checking.
