| hi, We recently bought a 4 8core 128G memory database server and I am setting it up to replace our old 4 4cores 128G memory database server as a master. The memory related settings that we use on the old machine seem a bit wrong according to the experts on IRC: max_connections = 600 shared_buffers = 32GB effective_cache_size = 64GB work_mem =
5MB maintenance_work_mem = 1GB wal_buffers = 64kB we are using ubuntu 10 /etc/sysctl.conf kernel.shmmax=35433480192 kernel.shmall=8650752 Can anyone suggest better values? thanks, Claire |
