comment Is it possible to use a partitionless EBS image as an HVM AMI?
I'm curious about how this would work. Do you have any further documentation I can refer to? The official AWS docs (docs.aws.amazon.com/AWSEC2/latest/UserGuide/…) state that "You cannot perform the rest of this procedure on a running instance" and my preliminary attempt to modify the partition table with parted gives the error "Error: Partition /dev/xvda1 is being used. You must unmount it before you modify it with Parted."

Editing the partition table requires taking the instance offline, detaching the root volume, attaching it to a second instance, doing the actual partition changes in parted, detaching the volume from the second instance, reattaching it to the first instance, and booting the original instance again. Correct me if this is wrong. This is not a dealbreaker, but it would be great to avoid this process the way we've been doing with our PV instances.

voretaq7: I was initially thinking along these same lines, since a typical request would also involve php/mysql, but the problem persists at the same threshold even when serving completely static content.

ceejayoz: I appreciate the suggestions, but fundamentally I believe that Apache should not be this slow. There are a lot of things we can do to mitigate the effect of the problem, but I would much rather fix or at least understand it.

comment Centralized virtualization (ESXi, XenServer) in a completely Windows-free environment
This looks very promising. The odd thing is that the documented workflow for deploying the appliance (unless I'm reading it wrong) requires you to already have a working Windows client in place before you can deploy the server. So far this seems like the closest option, but it still seems like an imperfect solution.
