Can you give me an idea why should I use the SMP kernel instead of Bigmen kernel [turn off the hyperthreading]? Will it be better to turn off ? > > grew up to 3.5 Gb and there were more than 160 concurent connections. > > Looks like your growing dataset won't fit in your OS disk cache any > longer.

But if I reduce the config to : max_connections = 160 shared_buffers = 2048 [Total = 2.5 Gb.] sort_mem = 8192 [Total = 1280 Mb.] vacuum_mem = 16384 effective_cache_size = 128897 [= 1007 Mb. = 1 Gb. ] Will it be more suitable for my server than before?
