Hi Matt, if you are using the HSQL EPSG database, this has most likely to do with the set-up of the EPSG database, which happens once per application start. Using a different database, like a preinstalled MySQL, where the EPSG content it provided, will usually reduce this startup time. Alternatively, if you know in advance which transforms you are going to need, you can store transforms directly (serializing them) and later recreate the MathTransform objects from that. AFAIR, you can also create a transform directly from WKTs, so soring these for the CRS you need might be an option.
