Howdy,

We have an Oracle database that is processing 500 transactions per second
during peak hours.  We are migrating this to a Linux VM running Postgres
17.6.  Is there anything out there that can give recommendations on CPU /
memory / shared_buffer sizing based on number of transactions per second
rate?  PGTune doesn't seem to have number of transactions per second as an
option.

Thanks,

Sam
