• Application Profiling: Memory Usage

  - by Abs

  Hello all, I have switched on the Codeigniter profile (very useful) and I have noticed that a page of mine shows the memory used as: 2,405,496 bytes That's ~2MB and it's for one request - does it mean if 1000 users accessed this page at the same time, memory usage will be 2GB? Have I got my maths wrong or is there more to this than just multiplying two numbers? Thanks all for any help

• Does the usage of interfaces slow down programs?

  - by Olga

  Is it true that interfaces slow down programs? I have heard that this is the case because during running time each during each usage of an object implementing this interface the decision has to be made which class implementing the interface this object belongs to. I am especially interested in an answer for C++, but also in general. And if this is true, some numbers would be helpful, too. Thank you very much!

• Random RAM usage amounts

  - by DTown

  I was hoping someone could explain why my application when loaded uses varying amounts of RAM. I'm speaking about a compiled version that uses the exe directly. It's a pretty basic applications and there are no conditional branches in the startup of the application. Yet every time I start it up the RAM amount varies from 6MB-16MB. I know it's on the small end of usage anyways but I'm curious of why this happens.
