If you know that switching to Saxon would mean 2-3x speedup then for
what you are waiting for? Other performance tuning tricks will usually
give you few percents, sometimes 10% or 20%. Definitively not 300%.

I think that relevant changes are part of 1.76. It brough 300% speedup
in xsltproc which doesn't have so good optimizer and around 30% in
Saxon. I haven't done any benchmarks on Xalan as I wouldn't recommend to
use it and it is very easy to switch to Saxon even in closed
applications due to JAXP XSLT transformer factory configuration.
