Hi Bob and others, do you have any idea why the 'print' and 'message' commands are very slow in the Jmol application (version 14.3.12_2015.03.01), at least on my system (OpenSuse 12.2; IcedTea Java 1.7.0_45, IcedTea 2.4.3; Intel(R) Core(TM) i5-2500 CPU @ 3.30GHz with 4 cores)?
I have for example three nested loops where the inner commands are run about a million times. The outer loop is run only 100 times. So I expected that a 'print' command in the outer loop giving a progress report (e.g. "10 of 100...") wouldn't have much influence on the running time. But I was wrong! With the 'print' (or 'message') command it took reproducibly about 43 seconds, without it only 23 seconds! This means about one second per five print commands. If this is not just the case on my system, I would suggest to add a warning to the scripting documentation that 'print' or 'message' commands can slow down scripts very considerably. By the way, Jmol doesn't report the Java information correctly on my system. It reports this in the popup menu: Java: Oracle Corporation Java 1.7.0_45 'java -version' reports this: java version "1.7.0_45" OpenJDK Runtime Environment (IcedTea 2.4.3) (suse-3.52.3-x86_64) OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode) Regards, Rolf -- Rolf Huehne Postdoc Leibniz Institute for Age Research - Fritz Lipmann Institute (FLI) Beutenbergstrasse 11 07745 Jena, Germany Phone: +49 3641 65 6205 Fax: +49 3641 65 6210 E-Mail: rhue...@fli-leibniz.de Website: http://www.fli-leibniz.de Scientific Director: Prof. Dr. K.
