[Xitami] Xitami/5 - new project announcement

[Russel Olinger]

I am curious - as I am not to familiar with LRWP - your description below gives me pause.  Does that mean that on a busy server every time a new URL is executed that a new 'instance' will be held in memory?  I completely understand the speed related to separate processes remaining in memory allow the next instance of that same url to run lightning fast - but how much memory is eaten up keeping these processes alive - and how does that affect over all system performance?  What if too many are held in memory - how does it manage new calls if memory is too full?

Thanks
