Bill Yes, I thought the posts were worth reading. Attaching the EF Profiler was the first that I saw, and is super-simple. All of Ayende's (blogged) testing was done in the month of August, 2010 - I searched carefully for something near the RTM time, but no. Perhaps in future. ________________________________ Ian Thomas Victoria Park, Western Australia

Have you done other metrics to compare such as a | |windows.forms app using the same data, and a Silverlight app using the same | |data ? | | | |As to advice: it's hard to say in your particular case. If you have an | |existing VB6 application, the first questions that need to be answered is | |what do you want to do with it, what are the goals of the migration? | |The "83 fields" part does make me wonder if this could be presented to the | |user better. Are you using tabs, logical groupings of fields? If so, each | |group in a tab should be able to load async / lazily. | | | |I wouldn't say that Lightswitch is only for web apps; rather I'd say its | |primary target is distributed apps. For standalone single user applications | |the architecture it uses is probably overkill, although there are benefits | |even in those cases to move the data to the cloud. For apps with the data | |stored in the cloud (such as Azure), I think Lightswitch presents a really | |low cost way of getting good quality data screens and letting the customers | |modify what they want | | | | | | | ||-----Original Message----- | ||From: [email protected] [mailto:ozdotnet- | ||[email protected]] On Behalf Of Kirsten Greed | ||Sent: Tuesday, 2 August 2011 8:08 AM | ||To: 'ozDotNet' | ||Subject: RE: Lightswitch - really clever - really slow | || | || | ||Hi Bill | || | ||The test app I created, released on my local computer, takes 5 seconds load | |the | ||data entry form. | ||Then 3 seconds to return to the list when I click the cancel button There | |are 83 | ||fields on the form. | ||This compares to less than half a second for my old VB6 application | || | ||I am running Windows XP SP3 | ||AMD Phenom(tm) IIX3 720 Processor 3.01GHZ, 3.25GB Ram Pyhsical Address | ||Extension | || | ||I also found the development experience frustrating because of the speed | || | ||Any advice?
