Hello, I'm running a CentOS 5.6 / 64 bit Linux with PostgreSQL 8.4.8 and Drupal 7.4 on a 4GB quad-CPU machine. In Autumn I can change my hoster and for EUR 100 can either take 1) 2 machines with i7-920 Quad-Core 8 GB RAM, 2 x 750 GB SATA-II HDD (Software-RAID 1) or 2) 1 machine i7-980X Hexa-Core 24 GB RAM, 1 x 1,5 TB SATA II What would you prefer? I know, the usual answer is "you don't provide enough details", but would it really help anyone if I provide all the details and print here all my scripts? My current setup - postgresql.conf: max_connections = 50 shared_buffers = 1024MB and unix pipe only (for 2 machines I will have to switch to TCP at 100 Mb/s switch). I use pgbouncer with pool_mode = session server_reset_query = DISCARD ALL; server_check_delay = 10 max_client_conn = 200 default_pool_size = 16 and at peak times it reports: 70 req/s, in 11616 b/s, out 784748 b/s,query 89556 us 34 req/s, in 5484 b/s, out 176943 b/s,query 60871 us 45 req/s, in 17976 b/s, out 169849 b/s,query 66496 us 53 req/s, in 10961 b/s, out 648585 b/s,query 40546 us My httpd.conf: <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 120 MaxClients 120 MaxRequestsPerChild 4000 </IfModule> Thank you Alex -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
