[Paraview-developers] slowness getting even slower

[Biddiscombe, John A.]

Robert

I believe I've located a fix.
in startup project add Environment setting
_NO_DEBUG_HEAP=1
which should give the same speed as starting without the debugger then attaching afterwards. Fingers crossed.

I'm just waiting for a rebuild (unrelated) to try it out

Hi John,

The collaboration changes have increased the usage of STL inside the ParaView codebase. Because of this you will see a slow down while debugging under Windows as debugging the STL is very slow. I would recommend that you launch ParaView outside of Visual Studio and than attach the debugger to the running process.

I did a git update this morning to get the new processmodule changes (first time in a month or so).

When running paraview inside the visual studio debugger, it takes over a minute to launch. Plugins add ten seconds or more each.

Without the debugger attached, it loads in 3 seconds.

I notice also that all plugins are actually loaded twice. I'm trying to debug that now because I get two of every dock window/panel etc.

(I have previously recomiled using the various _HAS_ITERATOR_DEBUGGING settings, but they make no difference.)

I have no idea what's going on, but I welcome any suggestions.
