I have a huge table with 14 field and few million of data... My application Php/Pg start to be impossible to use. Redhat 7.3 Dual PIII 900Mhz System 2GB RAM I did already a some optimization optimization : max_connections = 64 shared_buffers = 32000 sort_mem = 64336 fsync = false --- echo 128000000 > /proc/sys/kernel/shmmax also Vaccum,analyze and Index --- This optimization was enough at the beginning but NOT now with some million of instance. So WHAT I CAN DO ??? USE ORACLE ??? I Think maybe to split my mean table to different table Mean_a Mean_b ... Mean_z ??? IF it's the way someone where I can find doc or help about howto split table ??? I M lost !!! ;) Areski
