Our developers run on MacBook Pros w/ 2G memory and our production hardware is dual dual-Core Opterons w/ 8G memory running CentOS 5. The Macs perform common and complex Postgres operations in about half the time of our unloaded production hardware. We've compared configurations and the production hardware is running a much bigger configuration and faster disk. What are we missing? Is there a trick to making AMDs perform? Does Linux suck compared to BSD? Thanks. ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org/
