For all of these longer reports I RDP to the PSQL server and run them locally. They run much faster that way and don't tie up the local machine. The reason for this is that DBA/Evo iterate through the reports as individual transactions rather than as a query to the database. Therefore, each transaction has the latency of the round trip through your network, plus the latency of the local machine, plus local antivirus (as well as any on the network) and is subject to being throttled by software or switches. All of that overhead is removed when the reports are running locally.
