Re: Debug stepping speeds

["Tarr, Kenneth" <Kenneth.Tarr@xxxxxxxxxxxxxxxxxx>]

Thanks for the reply.  When the debug kicked into "overdrive", there were no changes to those tabs at top (Variable, Breakpoint, Monitor and Program were the only tabs up there, and it was on the Variable tab at the time).  It just suddenly jumped from about two lines per second to ten, which matched the settings I gave it.  I also added some additional monitoring of variables to add to the load yet it performed well.  The only thing different?  I had stopped, then restarted the debugger with the same configuration.  I've done that numerous times before and got the same slow pace...but then yesterday, it was blazing, and it stayed that way for the afternoon, despite stopping and restarting several times.  I will continue to document this to see if there is some key event I am triggering to cause this sudden burst.  (I should also add about yesterday that, when it switched from one program to another during the debug, the level (or number) of variables undoubtedly changed, but it was still zipping along nicely.)

Hi Ken,

I am glad you like the Animated Step debug feature.
A common cause of a slower than desired stepping speed is having debug views open that require more data. If the Variables view is open, for example, then as part of each step, the debug engine needs to read the debug information for all the locals and send any changes back the UI.
Similarly for the Registers view.
If you are interested in local variable values (or registers) as part of your animated stepping session, you could try monitoring the specific variables (or registers) you want to see and then showing the Monitors view instead of the Variables view. That way, only the changes for the locals you have a direct interest in will have to be sent back to the UI.
Of course, even with every view but the Debug view hidden, the ability of the UI to issue the next step command is dependent on the remote engine replying to the current step request. Network and server load could be playing a larger part in the slowness than anything else.

I hope this information is helpful for you to optimize your Animated Step use!

Good luck.
