Hi all,
I'm busy evaluating PostgreSQL and I'm having performance problems on one of my servers. I have a very simple one table database, and the client using Mono 1.2.5.1 is running a loop doing INSERTs on the table. Initially I tested this on my development PC, an old P4 system with 2GB RAM and 10,000 INSERTs took ~12 secs on average, which I was fairly satisfied with. I then moved everything over to our test server, a new Dell 1950 server with quad core Xeon processors, 4GB RAM and SCSI hdd expecting to see better performance, but instead performance dropped to ~44 secs for 10,000 INSERTs. This obviously is not acceptable. Both the PC and server are running the exact same PostgreSQL version, Mono version, client application and both tests were run under very low load and on an empty table. I noticed that CPU utilization on the Dell server is very low, 1-2% utilization, so obviously it's not a load problem. Only the test application is accessing the database.
So my question is, can anyone please give me some tips on what commands or tools I can use to try and pin down where exactly the performance drop is coming from? I'm obviously new to PostgreSQL so even basic checks can be relevant.
Kind regards
