I can't explain why it was topping out at 85 when it was set to 600, but
- I strongly recommend that you switch to a connection pool and lower
your max_connections considerably. You'll likely get much better
performance with max connections at 20 or less - the usual rule of thumb
is 'num_hdds + num_cpus' but in reality you need to benchmark and tune
to work out what's best.

pgbouncer is a good light-weight pooling option.
