Hi Folks,
Back in the '80s we configured swap space to be 1.5 x RAM as a rule of thumb. But I'm configuring 6 boxes now that contain 64-GB of RAM and I'm wondering if swap should be anything close to 96-GB. The boxes have only 128-GB of SSD for the operating system, so I'd like to minimize swap as much as possible.
Unless the 64 GB RAM boxes are really, really busy I do not think you need swap.
We've "tuned" the four Gig-E interfaces to input 950-Mbits/sec continuously. The boxes don't have to do very much except hand the thousands of 4-GB files off to the RAID controller. So throughput will be close to 500-MB/sec. I've measured a continuous record rate of 1.6-GB/sec to the RAID, so we shouldn't have any issues. Hibernation won't ever happen. I think I'll try it with 4-GB of swap and see what happens. Even if we had 64-GB of swap, considering our requirements, any serious swap usage would kill us anyway. Thanks for all the suggestions!
