Hi Tim,
First, the Javascript engine of Internet Explorer is effectively the
slowest one.
But, XSLTForms v1 is also using the native XML engine of each browser
and, for both Internet Explorer and Edge, it is still MSXML, which is a
COM object. It appears that it is, again, the slowest one with DOM API,
probably because it is not embedded in the browser itself.
XSLTForms v2 is using Fleur, which is a Javascript XML engine. For
loading big XML files, such as some XQuery test sets ;-) , in Internet
Explorer, Fleur parser is already almost as fast as MSXML. When
refreshing, because of MIPs and dependencies to be memorized, a lot of
xsltforms-* attributes are added by XSLTForms v1. For XSLTForms v2,
userdata property is directly used within Fleur Node object. I don't
have yet performance reports for forms refresh with XSLTForms v2 and Fleur.
Specifically for Internet Explorer, sorry, I have no idea for
performance improvement which could already be applied to XSLTForms v1.

Hi, Alain,
A quick question. I have a very simple form whose purpose is to
display an XML report (150KB). It can be accessed here:
http://bibfram.es/basex/static/test/index.xml
This is running in Tomcat7 in a BaseX web app.
The XForms Cumulative Refresh Time is essentially the same in Firefox
and Chrome: 695ms in FF and 669 in Chrome. However, in Internet
Explorer, it skyrockets to 4471ms.
Is IE really that bad, or is there something that I can do to optimize
performance for this browser?
Best regards,
Tim
