So I found some PHP Framework Benchmarks on this frameworks' site. A callgrind of FuelPHP got me thinking that if we had a command line tool that would merge cascaded classes into one file before deployment would really make the framework faster, Does anything like this exist?
But if you think this is such an issue: I run all my apps of a centrally installed fuel installation (so core and packages are not part of the application install), and I use a ramdisk for that (a few Mb will do).
I don't think it's an issue, it's just something that would probably be relatively easy to do, and would ease the load a lot for serious projects. Armadisk is a nice idea, but don't you lose the changes every reboot?
