    基本上是 2.6.x,因为 ubuntu 系统预装了,而且比较主流
    有台windows服务器因为依赖的模块只有 2.5.x 的,只好装 2.5 的了

    可以试试pypy.org
    mailing list原文

    Summary: Pypy 1.7 is almost twice as fast as cpython 2.7 on the
    tornado HTTPServer benchmark, and three times as fast on the
    template-rendering benchmark. Pypy used about three times as much
    memory in both cases, but usage was stable over time (i.e. it's not
    "leaking" like pypy 1.6 did).

    Details: Tested on an "m1.large" EC2 instance running ubuntu 10.04
    and the 64-bit binary releases of pypy (and cpython 2.7 from
    https://launchpad.net/~fkrull/+archive/deadsnakes). Large instances
    have two cores so the ab client wasn't competing for cpu cycles with
    the python process.

    @mlzboy virtualenv -p /usr/bin/python2.6
    -p 是 --python 故也可以用 --python=python2.5 这种格式

    p.s. virtualenv + pip 乃是王道~~ 远程部署再加上 Fabric 就完美了
