lengthy loading time

[Victor]

I am directed here by Eric Richards from the MS Infopath team.

I am currently developing infopath via form server integrated with
Sharepoint (WSS) v3. However, the form seems to take pretty long time to load
on a browser (~20 seconds on a 2.8GHz 1GB RAM laptop / ~13 seconds in a
2.66GHz 1GB RAM desktop). After some detail investigation, it seems like
loading the User Information List, a predefinded list from the sharepoint
main site, takes around 5 seconds. This data source on the Infopath is only
edittable by the WSS administrator. Views, and repearting sessions with
controls seem to have no factor on the speed. So, what causes the lengthy
loading time? Second, it seems like the sharepoint library does not complain
about the C# codes initially when I upload the xsn file to the form template.
However, the codes NEVER get executed!! Those codes are simply codes like
CreateNavigation.selectSingleNode(...) I checked the form option in infopath
and everything seems alright. Does the form server support C# coding with
infopath?

Thanks,
Vic

On the performance question: take a look at this whitepaper -
http://msdn.microsoft.com/library/d...bleshootPerformanceBestPracticeGuidelines.asp

Infopath Forms Services supports C# and VB.NET managed code; however, form
templates that use code must be approved by an administrator (follow the
publish wizard: File | Publish in InfoPath design mode)
