Having lived through the hell of IB5.X and trying to make
that stable, I am used to monitoring activity as a matter of
routine. I have 20-30 machines accessing via PHP on the test
network, but I'm not seeing anything that concerns me yet. I
could well agree with those statements for Interbase, and it
was probably not simply PHP going wrong.

That said, PHP5 has had a lot of work done on the interbase
module, and once that is complete I will up the load on the
test rig and see what happens. Rather than running 2 to 300
hundred trains an hour we can switch to 2000 per hour with
30 active stations :)

I also have a machine running a demo copy of ibWebAdmin and
while it is only running on an ADSL link, it's starting to
see some heavier use, and I can switch persistent
connections on their later so I can monitor it. ( They are
off on that at present ).
