Hi Ashley,
as said before, with JAI-EXT enabled I'd expect bilinear scaling to be
slower (while for example we have reports
that bicubic warp is faster, it depends on the operation), but since you
have a test ready, try it out and let us know how it worked?
All the "native accelerations" will be off obviously, as those require
"native jai" to be installed and
jai-ext to be turned off.
Basically, keep the defaults that you have
Cheers
Andreaù
