I have a function in pgsql language, this function do some select to some tables for verify some conditions and then do one insert to a table with NO index. Update are not performed in the function When 1 client connected postgres do 180 execution per second With 2 clients connected postgres do 110 execution per second With 3 clients connected postgres do 90 execution per second Finally with 6 connected clients postgres do 60 executions per second (totally 360 executions per second) While testing, I monitor disk, memory and CPU and not found any overload. I know that with this information you can figure out somethigns, but in normal conditions, Is normal the degradation of performance per connection when connections are incremented? Or should I spect 180 in the first and something similar in the second connection? Maybe 170? The server is a dual xeon quad core with 16 GB of ram and a very fast storage The OS is a windows 2008 R2 x64 Thanks Anibal -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
