Disabling open_basedir while also disabling symlinks in PHP and ideally

Adding a local disk is almost certainly a fix, if possible.

Making a RAM-based filesystem to cache that part of your disks might be
a possibility, if you can separate out anything thta changes state
whilst the service is active.

Those are god ideas, Dave, but they really patch over the problem, which
I think is a design/architecture one:

The point is what can Per change with reasonable effort versus what can
Rasmus and friends sensibly fix (given that they've shown no signs of
doing it for up to a decade (depending how you measure).

Why do I know Perl and not PHP? It's not a coincidence.

Cheers, Dave

Why is it lstat()ing all those files every time?

Solve that and those 'patches' aren't critical.
I'm not saying that speed improvements like these are of no use, just
that a design/architecture change gets to the root cause and fixing that
is more bountiful.
