Most of that probably happened to the increase in the number of servers as well as the change of OS.

Well being as the new system is quoted as being 92 times faster, that would be a lot of new servers -- and might suggest they re-did their algorithm to be so scalable. In such case the speed-up wouldn't be accorded to the linux directly, but to the cheap cost of adding a new linux server.

Well yeah, if these were five year old servers: CPUs 4x faster, 20-100X the memory (no paging, THAT will do wonders), 4X faster disks, etc. 50-100X faster But it also means that cheap fast hardware means all but the most demanding and exotic IT tasks can be done very very cheaply now. Even RDMSs are open software now. Who cares if Oracle is twice as fast. That Oracle license can buy more $3000 servers than you could shake a stick at. If you IT manager wants to spend millions to get something done, start asking tough questions.
