My personal adventures in the quest for virtual perfectness.
Like: did you know VMware developed a tool called vmtar. A normal TAR is unaligned and vmtar makes sure the files inside the tar are aligned. Why do we care? Well, as the tar holding the core which makes ESXi tick are loaded into memory, some 'writable' files are copied to ramdisk. So the ramdisk and the tar are both in memory and somewhat the same. And there we have Transparent Page Sharing, optimizing the memory. If we didn't had vmtar, the tar files would be unaligned and TPS wasn't so effective - however, thanks to vmtar, TPS is more effective, saving more memory.
And THAT'S why I love VMware so much - not thinking: "oh well, servers these days have sufficient memory, why bother?", but: "how can we optimize memory and make sure we still use the smallest footprint!".
Also take a look at how the PCoIP is working on iPad, smartphones and other devices - this is NERD+ stuff! And I'm not finished reading this 80 page PDF!
So don't wait and start reading this whitepaper! Nothing else matters .
