Specs: Server RedHat 7.1 2.4.2-2 kernal everything build with Interchange 4.8
I am learning Linux and Postgresql from scratch. 1. Can someone point me to or explain any linux kernal optimizations for redhat that can made to maximize performance of a postgresql server? I have briefly looked at Momjian's performance recommendations for the postgresql database itself, but I wondering if there is more that can be done? 2. What RAID levels does postgresql support? I don't want to make any assumptions. I plan to put the data on an EMC Clariion FC4700 with RAID 10 eventually. 3. How much memory does postgresql require? Is there a best known method for size of memory in relation to the size of the database and expected growth rate? Is there a way to optimize memory i.e. page free space and page splitting - this may not be applicable but I have been tasked to research it. 4. How is Symmetric Multiprocessing Processor (SMP) configured? Can postgresql take advantage of SMP?
