Congratulations, Colin, and thanks for the nice XMas present. > it is a very good performance indeed (and about 1600 times faster than > Altova on selected stylesheets (on many Altova doesn't finish at all...)). Keep up the good work. I will find time to run all FXSL tests with Gestalt 1.0. -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play On Dec 21, 2007 6:17 AM, Abel Braaksma <abel.online@xxxxxxxxx> wrote: > Thanks Santa for you present! > > In lieu of today's (tonight's, depending where you live) discussion > about performance measurement, which is, as you pointed out, far from > trivial, I found the fast startup time of your Gestalt processor > remarkable.
