After converting an app from Mx6.6.0 to 6.10.3 (running on premise, windows with sql server db), users experience a slow performance. Simple overview pages and the upload/download/delete can take minutes.
A testrobot is executing basic functionality in the app (login,upload,search,delete) to gain performance statistics. The statistics point out that the performance of uploading a file (using dropzone) is reduced from 1250ms to 6000ms exactly after converting to Mx6.10.3. Also deleting a file is slower (3500ms to 7000ms). The performance of the other basic functionalities stay stable, so my conclusion is that the something has changed in the filehandling in Mendix that causes to slow performance of the app. The release notes between Mx6.6.0 and Mx6.10.3 only mention performance improvements....
(buying and implementing an performance tool will not be a customer's choice)
Does anyone has experience and advice with this problem?
Edit: The console does not show strange behaviour during uploading multiple documents via Dropzone. The app is being moved from on-premise to Mendix cloud and there is a good chance this solved to performance issue's.
