Hint: It is a software solution, not hardware...
It is easy, it is the RunFaster=1 switch in registry, just don't remember the correct place where to put it :)
Have you moved to Server 2008?
My guess is win2k8 and IIS7
My guess, you changed your hosting platform? Hyper-V by any chance?
my guesses: - they disabled a lot of unused windows services - scheduled defrag - clean installed windows -
Does that begin with R and end with R? :-) Must say it's super fast even on local dialup broadband.
Could it be that the answer is right on the home page?
According to Netcraft there was a recent switch to IIS 7. http://uptime.netcraft.com/up/graph?site=www.wssdemo.com
My guess is a headless 64 bit 2008 server running IIS 7.
Turned on Site Collection Administration -> Site Output Cache and Site Collection Object Cacheg
The server had been upgraded to new hardware, W2K8 and Hyper-v a few month agot. The big improvement has come from the Runtime Page Optimizer. See my next post...
Might be they got rif of some OLD lazy developers & replaced them with sincere & serious ones who can write code smartly :)
