Just a quick note regarding performance: on my ThinkPad T400 (Core2Duo
T9600) laptop, with only one nginx worker, and both ab and mysqld
running on the same machine, and no memcached and no result set
caching we get:

    Server Software:        nginx/0.8.41
    Server Hostname:        localhost
    Server Port:            1984

    Document Path:          /baz
    Document Length:        176 bytes

    Concurrency Level:      10
    Time taken for tests:   1.812 seconds
    Complete requests:      10000
    Failed requests:        0
    Write errors:           0
    Non-2xx responses:      10000
    Total transferred:      3900000 bytes
    HTML transferred:       1760000 bytes
    Requests per second:    5518.47 [#/sec] (mean)
    Time per request:       1.812 [ms] (mean)
    Time per request:       0.181 [ms] (mean, across all concurrent requests)
    Transfer rate:          2101.76 [Kbytes/sec] received

And with ngx_memc + ngx_srcache enabled, we can achieve 6200+ r/s with
the same settings.
