在win server上通过exec调用exe只能单进程么？不能并发调用吗？

exe php exec 阻塞 非阻塞 exec

php通过exec调用exe可执行文件都是单进程阻塞式进行的吗？我发现我本机多个浏览器同时请求调用，发现服务器只起一个exe程序。而我是想一次请求就调用一次exe的。请问各位大牛是怎么回事？或有其他的解决办法吗？

回复讨论(解决方案)

没试过 是否 exe自身就有判断

版主大人能不能帮忙解决一下啊？
每次通过php页面请求调用，都是排队使用exe，不管你有多少个php的请求。
php的执行不是并行的吗？为什么在调用exe时变成了串行式调用呢？
是因为采用fast-cgi的机制（所有的请求都在一个进程里处理）的原因吗？
