Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    # of users supported

    As the App Server utilizes only a single core, and is 32 Bit only, realistically how many users can be supported in a "Browser based" application.

    Re: # of users supported

    People ask this question all the time. It depends on the application, how intense the processing will be, backend database, etc. Neither Alpha nor any of us have a truly accurate answer. The only way to tell is to make use of a rigorous testing method. Someday, someone is going to hire a 3rd party company, or run a 3rd party tool specifically designed to test an Alpha Five web app in terms of multiple users and load. (I have a client about to do that to a new V10 app.) Those testing companies and tools exist. Unless you are willing to do that, you won't know the answer.

    The other legitimate answer is it depends on how your users interact with the website. The server will react differently to 100 persons performing continuous data-entry than 100 people browsing a shopping cart and maybe buying something. And in both cases, AJAX will make a big difference.

    And it depends on how well you construct the application. A bloated application will run poorly with one user online.

    I'd like to see benchmarks comparisons of Alpha, LAMP, .NET, etc.

      Re: # of users supported

      Hi Steve, my concern is all previous development I have done is Desktop. Before undertaking the WEB side, I need to know that the application will not need to go back to the desktop.

      There will be substantial processing being done.

      With the larger applications you have done, what do your users have with regards to concurrent users

        .NET will exploit how many cores, and how much memory ($$) you throw at it,

          I have a fairly intense Support Application running with over 100 users. The server is running XP Pro sp3. It is all intranet over vpn connections but it works remarkably well. Also, this is a v9 app.

            Steven,

            If you want to see it in action, I have a customer near you (in Aurora) that is running V10 with a MySQL backend. He is supporting 16 stores over the web, and he is willing to give you a demo either at his headquarters or by remote.

            He does some interesting things, like a full text search of 5000 documents in less than 2 seconds, and some of his tables have hundreds of thousands of records. It should give you a good feel for Alpha's capabilities in a real world setting.

            If you are interested, email me at [email protected], and I'll email you back his contact information.
