Hello Peter,
There is no specific reason for a select1 control to be slow. Probably,
there is a refresh just after selecting one item and the size/structure
of the corresponding instance might be the cause of this. The involved
XPath expressions might also require a lot of time, for example if the
// operator is used.
You can use the XSLTForms Profiler (pressing F1 to be in the Debug Mode)
and the native IE Script Profiler to locate functions/methods with heavy
execution times.
There are many ways for optimizing and I would need a testcase or a
remote access to diagnose.
Thank you for your feedbacks!

Dear List
I have a simple XForm using XMLSTForms rev 565 within eXist-db
version2.0. The form has a simple select1 control in it. The control
setting is selection="closed".
I am viewing the form on an IE9/Windows 7 machine. The IE9 is in IE9
mode, not one of the other mode options.
When the control value is changed the dropdown with the various
options stays open for some seconds and during this time there is
significant processor activity as seen in the Task Manager. I would
have expected the new selection of an option in the select1 box to
have been instantaneous.
Any ideas on what is happening, and how I can improve this to provide
an instantaneous change to the selection of a new value?
Many thanks
Peter
