Beta Team - directions to speed up Firefox browser

Team:

Based on your feedback we have already made improvements to Rally Navigator.

Just today we made programming updates to speed loading time and also improve the function of the rotating "Loading" icon, you will also see in the roadbook header a Status Bar with a readout of the track points as they load from the library. This lets you know things are progressing and not "Frozen" as some have reported.

Rally Navigator can run much more quickly on Firefox with the following configuration changes (which we strongly recommend).

Check out: http://www.planetinaction.com/speedtest/ For complete info and to Speed Test your system:
Google Earth plugin API speed test

This speed test issues a number of Google Earth plugin API calls for every frame drawn. The number of frames per second is a measure on how fast this is done. On a decent computer you should get 20 - 50 fps.
Speed things up 5 times or more...

If you are using Chrome or Firefox 4 or newer you should read this!!!

The Google Earth plugin needs to communicate with the Javascript code that runs in the browser. This means that there are two processes that need to talk to each other. This is called "Inter Process Communication" IPC for short. Browser makers have tried to make the browser more robust by treating the IPC calls with more care. That is very nice of them but someone forgot to consider the performance penalty.

Applications on Planetinaction.com typically make thousands of calls per second to the Google Earth plugin. If each of those calls takes a tiny amount longer you immediately suffer massive performance penalties. These can be in the order of 5 - 10 times slower that they should be.

Fortunately in Firefox you can turn of the IPC protection to the plugin. If you type "about:config" into your address bar, you'll get to a page with a lot of settings. Find the line for "dom.ipc.plugins.enabled = true" and toggle it to "false". Restart your browser and things should run much better.
I have had my personal computer set like this for months with no ill effects.

My Speed Test Results after the IPC configuration change:
Google Earth plugin version:6.2.2.6613
Average FPS over the recorded 10 seconds is: 61.65


While we are working to streamline Rally Navigator interaction with Google Earth this is a great improvement.


Rally Navigator works best on GE version 6.2, not the new 7.0

Get Google Earth 6.2 here



Please let me know if you have good results with these IPC browser updates and also the updates to the Rally Navigator code.

Also, take a look at a quick overview of Rally Navigator usage. Some users weren't clear on basic functions.

Sorry about all of the special configurations and set up tricks.....that's why they call it "Beta"!

Thanks to all testers,
Mike
