And yes, your system bogs down as more swap is used, because modern swap can not cope when set on rotating rust. You need to move it to an SSD disk.
No. If it is happening then it is symptomatic of something wrong. A faster swap with SSD wont fix it. It just speeds up the IO rate of the thrashing. Just like a faster CPU will speed up the rate at which the memory gets scanned for scheduling the IO. So what?
Like a ramdisk wouldn't fix it either, right..., in fact probably not memory either. Hrmph. Well saying 'fix' it, is a bit of a misnomer when the OS isn't broken. But if your swap is as fast as memory at a good 2-3GB/s, its defintely gonna help -- alot.
Right. That's the idea.
A PCIe (sits in a motherboard slot instead in harddisk form) would help drastically, but better would be to increase main memory.
Ah, that I just did :-) I bought a new motherboard with 32 gigs. Know what? It uses swap, this afternoon 3.5 gigs. Tracker something was using 1.5 gigs. Then I had to zypper up and reboot. Well, it uses swap because I hibernate it. And when it wakes up, things that are not used remain in swap, for days if need be. Even if there are 22 free gigs of RAM. -- Cheers / Saludos, Carlos E. R.
