Hi, I've got PG 8.2.3 running on a dual-core P4, and I noticed that, at least during reindexing, postgreSQL REINDEX process is using only 1 of those 2 cores. You can clearly see this from this snippet from top: Cpu0 : 93.3% us, 6.7% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si Cpu1 : 0.0% us, 2.6% sy, 0.0% ni, 85.5% id, 11.8% wa, 0.0% hi, 0.0% si PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 21909 pg 25 0 116m 89m 42m R 98.9 9.2 1:01.92 postgres: pg mydb [local] REINDEX This PG 8.2.3 was compiled from sources on this box, so if there is anything in the config/install process that should pick up that this box has "2" CPUs, perhaps that didn't happen? I know I didn't manually instruct the config/install that the box is a dual-core box. This is running on a Linux box with the SMP-aware kernel. Is this a known limitation? Am I reading this wrong? Thanks, Otis
