如何减少cpu和ram的使用？

Question

I'm going to "read" (video/big) files from a server (shared environment) to clients (webbrowsers) via PHP and would like to know first if there is a way to reduce CPU and RAM usage somehow (as I have those limited).

Answer 1

if there is a way to reduce cpu and ram usage somehow

Not really: You'd just have to stream the video through (using fread() in small chunks) instead of reading it into memory in full. There is little space for optimization both on the RAM and the CPU end here.

That said, it is not very good on performance to stream video through PHP, and as I've already said today in a similar question, if I were a server administrator, I would frown upon that kind of activity. If at all possible, you really should consider using a normal download, or specialized streaming server for this.
