Dunno! You have an XS-on-XO SD card? You look like a candidate to
experiment and benchmark ;-)

[ In general, we're memory and i/o bound. So if it reduces memory
footprint or disk IO it's a win. If not, it may be a marginal win...
and we enter complexity/benefit tradeoffs. OTOH, if it's tuned to
super-scalar CPUs it won't be pretty. ]

[Server-devel] hiphop for PHP

2010-03-18 Thread Sameer Verma
This came up today at OSBC conference's keynote by the Facebook guys.
FB processes its PHP to C++ and then compiles it. Approx. improvement
on CPU is 50%. Will this be useful for XS, especially on boxes with
lesser resources?
