Performance AutoCAD 2010 update 1 with .NET application very bad.

[marco]

Hello,

I installed Update 1 to AutoCAD 2010 recently and noticed the performance of my .NET application decreased dramaticaly.
I built in some stopwatches to test on both plain AutoCAD and the updated version (on the same machine). With update 1 installed the application needed up to 3 times more time than in plain 2010.

Has anyone else experienced this and does anyone know why this is happening?

I've had no reports of anything like that, but it most likely
depends on what your app is doing. Is it using the command
line? If so, how? What else does it do?

The application we are building uses a ObjectEventHandler to respond to changes of dynamic blocks.
When an object is changed first we check if it's a dynamic block. If not the method stops.
If it is a dynamic block we read it's XRecord data and dynamic properties.
The Xrecord data is used to change attribute values, layer and color of the BlockReference.

No other user intervention is needed except for changing the dynamic properties.

We hunted the performance loss down to the reading of the XRecord data.

How much xrecord data is there?

Depending on the blockrecord it can be quite a lot of records. The content of the records is just some short strings,integers and doubles.
I attach a XML/structure with the data of one blockrecord.
