Yes, well I assumed: 1) this was i386 2) he already had a lot of RAM and was hitting the wall my point was primarily to point out that he shouldn't assume ram + swap must be under 4GB. Otherwise I agree. Though, I typically have a large MFS /tmp directory. Having lots of swaps helps make that configuration robust. -Jon On Thu, 7 Jul 2005, Kris Kennaway wrote: > On Thu, Jul 07, 2005 at 02:57:01PM -0700, Jon Dama wrote: > > It is also it is worthwhile to remember that on i386 you can use > > roughly >20GB of swap space. swap + ram need not sum to less than 4GB > > common misunderstandings aside. > > > > If your memory load warrants larger swap allocations, you should just bump > > that number up. > > Better to add more RAM or reduce or optimize the workload - as soon as > you load your machine enough that it begins heavily using swap your > machine performance will fall in the toilet. > > Kris >
