禁用 Lua 代码缓存（即配置 lua_code_cache off）只是为了开发便利，一般不应以高于 1 并发来访问，否则可能会有
race condition 等等问题。同时因为它会有带来严重的性能衰退，所以不应在生产上使用此种模式。生产上应当总是启用 Lua
代码缓存，即配置 lua_code_cache on :)

lua_code_cache on 用ab测，有时成功，有时提示
# ab -n 200 -c 100 localhost/mongo
debug日志最后一个请求发送完之后shutdown失败，难道是ab的bug？

你的 worker_connections 配置为了多少？Test::Nginx 生成的配置中默认是 64，或许和这个有关系 :)

我见过在一些系统上的某些 ab 的版本有问题。你可以尝试换用 weighttp 工具:
http://redmine.lighttpd.net/projects/weighttp/wiki
另外，在测试时可以考虑启用 http keepalive，以免测试工具耗尽动态端口。

这个出错消息是无害的，其 info 级别也指出了这一点。它是指当前的下游连接已经提前断开了，所以 nginx 一侧再 shutdown
时就会报这个 ENOTCONN 错误。
你的 nginx 错误日志中还有其他 warn
以上级别的出错消息么？另外，启用调试日志会对性能产生很大的负面影响，进行性能压测时尽量避免使用启用了 --with-debug 选项的
nginx.
