Hey, I just rendered [[Barack Obama]] in about 6

is HHVM is the whole story, but that's a fabulous improvement towards the
usability of our largest pages.

would require me weeks to complete, even with the improved
automation we built lately.
Thanks to the incredible work by Yuvi and Alex, who helped me basically
around the clock, today around 16:00 UTC we removed the last of the
mod_php servers from our application server pool: all the non-API
traffic is now being served by HHVM.
This new PHP runtime has already halved our backend latency and page
save times, and it has also reduced significantly the load on our
cluster (as I write this email, the average cpu load on the application
servers is around 16%, while it was easily above 50% in the pre-HHVM
era).
The API traffic is still being partially served by mod_php, but that
will not be for long!
Cheers,
Giuseppe
