We found that we were making database calls that weren't necessary when viewing GPS history data by Route in GPS Control Room. After removing the call, we found it loading over 15 times faster! 65 seconds of load time before the change, and just over 4 seconds after the change. Note this was over a VPN connection, my initial load time would have been closer to 15 seconds had I been in the same network as the SQL database server.
We want to do some more testing before releasing this version. Not all the information in the route entity information panel is showing up like it should.
