Re: How to use zram ?

I'm trying to wrap my head around what the performance implications (or
advantages) of zram might be in the virtualized environments. Currently for
me that means mostly VMware and a little Xen. There are at least two
aspects, namely its potential use in the hypervisor and use in the VMs.
Does anyone have any guidance on this issue?
Second question: Do we know how the AWS-branded linux AMIs make use of zram
if at all?
Thanks.......Nick G
