The driver DLLs are now simply kept in memory for the entire process life time by skipping the FreeLibrary call. It turned out that loading/freeing shared libs is the major cycle hog (everything else done in plinit() is negligible in comparison), even if the modules in question have previously been mapped into the proces. Now LoadLibrary() just returns the handle to the already mapped module.

You might try using plend1() instead of plend() when you finish the 
plot. This also keeps all the shared libs in memory so that plinit() 
does not have to reload them.
