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
