[Answer]-Virtualbox linux guest with apache and django is too slow

The problem is Windows host directory.

When you request a file from Apache it will most likely fork a new UNIX process which need to load the whole Python + Django stack to memory. Doing this roundtrip file system reads over SMB networked file system from Windows partition which is very expensive.

My suggestion is to have all files inside the guest OS and that should bring up speed up a lot.

Alternative ditch Windows altogether and run your whole development environment inside the guest OS.
