I was trying to use fpassthru to runing a fileservice web host. 
But when the web server request at a large scale, like 100 more requests for different files at same time. The fpassthru() bring the server load up to 30 even 150, and OS have to use large amount swap to fullfill the buffer request from fpassthru(). Which we all know its extrem high for unix system.

We all know unix provide an easy way to output file data via sendfile() which avoid resouce copy between users but direct cope filepoint to socket. 

I know its might be diffcult to oprerate on webserver socket from PHP as FCGI or mod. But I really hope there is another way to improve fpassthru() to some real large scale usage. Otherwise I have to rewrite a httpd by myself to server for dymatic file service request. :(

Does this issue still persist? PHP 5.1.1 has been quite a while

BTW: can't you use readfile()?
