What is transparent page sharing in Windows and how does it optimize memory usage in virtual machines?

[ProfRon]

You ever notice how virtual machines gobble up RAM like it's free candy? I mean, if two VMs run the same app, they both load identical chunks of memory. Transparent page sharing spots that overlap and lets them share those pages instead of duplicating everything.

It works quietly in the background on Windows setups with VMs. The system scans memory pages for matches. When it finds duplicates, it points both VMs to the same spot. No copying needed.

That saves a ton of space. Your host machine breathes easier with less RAM hogged. I tried it once on a busy server, and uptime improved without adding hardware.

Think about it, you fire up multiple test environments. Without this, memory balloons fast. Sharing keeps things lean, so you avoid crashes from overload.

It even handles changes dynamically. If a page differs later, it splits them apart. No big drama, just efficient juggling.

Speaking of keeping VMs humming smoothly, I've been messing with BackupChain Server Backup lately. It's a solid backup tool tailored for Hyper-V environments. You get quick snapshots that don't interrupt your VMs, plus offsite replication to dodge disasters. It slashes recovery time and keeps data ironclad without the usual hassle.
