Adding Speed to a GPX file

[routeconverter]

I observed that if I had a file open in RouteConverter and then opened the SAME file in RouteConverterPrerelease and, in the second file, asked that the program inject the speed into all 44,736 positions, the file scrolled from the beginning to the end as the speed was added to all of the positions rather quickly, with NOTHING visible on the left side of the screen due to the use of that same data using the jar in the regular RouteConverter.

RouteConverter can only be started once with a map displayed on the left. That's a limitation of the underlyinging JDIC library and caused by a lock on the IeEmbed.exe binary used to embed the Internet Explorer.

Is there any way to add the speed quickly by telling the program NOT to display the map view until the speed has been added to all the records?

No. But if you reduce the size of the map by clicking on the arrow to the left, I think no updates on positions hit the map component and force it to update.

What is the problem that causes the speed to be added so slowly when the map is displayed and very quickly when the map is not displayed?

You're updating every single position of the track, forcing the map component to update the map view each time since it cannot determine (Java ListModel stuff #§$%!&"!) that there is no need to update as only the speed has changed which is not displayed anyway.

[I've also observed that I cannot get any email while the program [javaw.exe] is hogging my link to the Internet, and that it is using over 300,000 Mb of RAM and running at almost the full capacity of one of the processors in my computer, with no sign that it is near completion of adding the speed to those records... and no way to tell the program that it cannot hog the resources this way.]

You're performing resource extensive stuff on your machine

Added... The number of decimal places in the added Speed line in the resulting GPX file needs to be limited to 5 decimal places.

I do not find anything about a limitation of the number of digits in http://www.topografix.com/gpx/1/1/gpx.xsd - where is your information from?
