[GENERAL] about memory size reported by system.
Hi everyone! I have a doubt about the memory consumed by each connection open. suddenly my server, running postgres 8.3.11, began to run too slowly. Checking the process with: ps -adelfo pcpu,vsz,args | more The processes,related to the connection to the db, each one have a consume of memory near to the 50Mb. by the way i have 50 connections to the db, so i have a reported memory consumed of 2.5M, when i have only 1G in the server. If I modify the shared_buffers value, the report of memory consumed is according with shared buffers value. Should I worry by that? There is a best way to tweak the memory consumed by postgres? -- SENSA Control Digital. Ing. Edmundo Robles Lopez.
