Its a web search engine with 10-15 search options, so yes the selects will vary and very often every row will need to be examined. Also as I mentioned the ramdisk will be used to speed up a very long insert/optimize batch. Thanks for the tip on the tempfile! > There are hardware based RAM cards that don't steal memory from the OS, that will solve the problem but are > still fairly expensive. Yeah they also defeat the purpose of using Opteron chips with on-chip memory controllers for high memory bandwidth. The only advantage of those cards that I know of is that they have a seperate power supply so they are less risky, but we will be backing each update up to disk anyway. I understand Linux's ramdisk implementation is stable, we are also using ECC ram. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
