    [CLOSED] From V2 to V4, performance

    One of our web/application is used daily by about 300/400 users.
    Do you think we would have improved performance by migrating to version 4.

    We already have the license but we are using it only for new applications


    Thanks

    Hello @ADV! This is extremely uncertain to say whether you are going to get a boost or a shrink in the performance.

    It heavily depends on which components you use and how you use them, that's very hard to predict up front.

    By one hand, newer Ext.NET versions introduces optimizations on components or aspects that had slow performance in previous versions. By the other hand, we have improvements, new functionalities, and even bug fixes that can introduce extra overhead in the process.

    As an example of improvement, the event handling has been pretty much rewritten to support (and better support) mobile devices.
    To name a new functionality, we have new themes, they can be faster in some aspect (as Triton using the Awesome font for glyphs), but also slower for others (more complex & elaborate CSS formatting).

    Another very relevant set of improvements is the charting functionality. It was much less responsive in 2.x series, and a massive change took place between 2 and 3, and still some more improvements (like pie3d charts) from 3 to 4 (the 3D charts looks much nicer!).

    In general, we encourage our users to upgrade the software, as Microsoft would recommend you to upgrade from one Windows version to another for at least -- but not limited to -- the reasons below:
    - continued support (we fix many bugs in new versions, some bugs in older versions sometimes are only viable to be fixed in next releases, and old versions become progressively hard to support nowadays technologies and trends)
    - modernization to nowadays environment (devices, look & feel, tools)
    - new components just can't be introduced in old releases to avoid breaking changes

    But there's always implications on upgrades. Using again the Microsoft product example, from windows 7 to windows 8, there was a hardware requirement that prevented old PCs from having the upgrade (without some hacks, maybe). They required what they call 'NX' or 'execute disable bit' support in processors. Older processors and Intel Atom powered laptops for example, were unable to upgrade. Likewise, newer Ext.NET versions will require newer libraries and depending on your application, increased server power to handle the new technology it brings.

    One thing you are certain to have during a legacy software upgrade is issues. Some things just don't work as they used to be in the past.

    But you also have us to help you solve them! So, bottom-end, we encourage you on upgrading to latest Ext.NET 4 and will do our best to assist you in any problems you face during the upgrade process!
