I have an issue (I think) with my SharePoint 2010 ADO.NET Data Services.
I understand that using Data Services is an extra layer and as such might inhibit performance a little, but I was not expecting what I found.
I am running SharePoint 2010 in a VMWare machine on an SSD drive (Windows 2008 R2).
Currently, requesting mt lists of lists takes 0.5 seconds consistently, even though it's only a collection of 20 list names:
Server Object Model, this takes 0.05 seconds. ADO.NET seems to be 10x slower Obviously the overhead might be flat and at higher volumes plateau at a 0.4 second overhead regardless. But it's still slow in my opinion.
I have done a lot of tests of serializing XML, custom WCF services etc. and nothing seems to indicate that such a small results set should take so long to load.
Any suggestions would be incredibly welcome!!
Or is this the performance I should expect??
What do other people get?
