mod_perl中关于apache::DBI,可能有人不懂

Apache:BI improves the performance of DBI by caching database connections. Opening a connection to a database often takes a lot of time, so Apache:BI maintains a cache of open database handles. As long as Apache:BI is loaded before the DBI module, all connect requests will be handled by Apache:BI. One limitation of the cache: You cannot create database connections in the parent Apache process and have them shared by child processes.

你想说明what?这里主要说明的一点是不要在父进程里创建Apache::DBI对象,否则fork出来的子进程都来竞争这个DBI句柄的话,就会造成阻塞,违背了Apache::DBI的本意.
