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.

    Re: Massive Number of Users Login Concurrently

    I expect to do that, but I'm not there yet. I, too, was an early beta tester, and after a dozen tries couldn't even get a full publish and had to set it aside. I need to come back to this and try again -- that was a year ago.

    But one current situation is a customer with a heavy load and looking to IIS as a solution. Given the time and money commitment to even building a test environment, it's not the best idea to just tell my customer "we have to test it to see what's in it." Having some objective measures or comparisons from other users of the Alpha IIS plugin would go a long way to deciding to commit to that path, time and expense.

    If you don't have information like this then fine, I understand. But does anyone?

      Hary,

      Seems like everyone's answer is spend more money, but your post says money is tight. So, without more money, what can you do?
      First, make each login as fast as possible. Try to get each user on, logged in and signed off as quickly as they can.
      Second, make the login component as lightweight as possible. Don't use images or grids. Use a simple CSS and Viewbox.
      Third, if any money is available, add more memory to the server and add another instance.
      Fourth, try to spread out the logins if you can with some people asked to login earlier and allowing others to log in late, say 10 minutes early and 10 minutes late.

      Good luck!

        Re: Massive Number of Users Login Concurrently

        I have only done one load test on one Alpha with IIS installation and maxed out at 120 concurrent users with a 10 second response time threshold. I was hopping to get additional input from others.

          Throughput is the primary reason IIS outperforms Alpha Server as the number of concurrent users grows beyond 25 or 50.

          IIS is multi threaded and multi process. From another post I found this "According to Selwyn, you will not likely see any performance benefits when the server is not under load.
          The benefit of IIS is a result of machine utilization, meaning better performance under load.
          So if you had 100 simultaneous users running on a multi-core machine, you will get better throughput on IIS than you will on the Alpha Server."

          Perhaps here is the best explanation http://www.alphasoftware.com/blog/ii...er-utlization/

            Also notice upcoming and past devcon where Selwyn presented idea's about moveing in time frames all xbasic to node.js is a matter of choices eq TCO and ROI and your time given.
            And do not forget infrastructure is your best frend in this matter .
            A good response acknowledge even with heavy load should be less then 10 seconds perhaps 3-5 what is as accepted for custom behavior

            Back to the original post question at the top if u need to serve up to 2600 users there a price to pay as AA services upto 5 cores [ see answer response] and Steve Wood his test results.

              Re: Massive Number of Users Login Concurrently

              I really wonder what are the benefits of IIS integration. If I understand right the integration is build using 4.x .net so it is already a legacy system. In recent years all Microsoft developers have been waking up in some morning just to realizing that he/she is using now legacy development system. Now all Microsofts eggs are in Net Core but it will still take years when it is ready. Maybe then we have version 7 going and then something again and again and again.

              I also wonder what happened to the Alphas plans of using javascript in server side. Now it seems to me that we are totally stuck to Microsoft. Are we in good hands? Is there any innovation in web/mobile side that is from Microsoft today?

                  Another avenue is AlphaCloud. Talk to Alpha about this.

                    AlphaCloud is even more "cloudy". How do we know anything about performance there (bang for the buck)?

                      I wonder if Alpha would provide a way to get Steve Wood's test onto the AlphaCloud, and let Steve run the same load testing against that?

                      It seems reasonable to assume that Alpha Software has load-tested their services, and this would add to the data.

                        Just checked the thread and so many input from many ppl thank you very much, it is as Pat said that i had enhanced the login component as light as possible and make more instance as Steve suggested (without load balancer and without more servers) and I divided the apk between group of users thank God the system better now. As for Eric suggestion i will try to test it first internally Thank you guys for the Great Input!!! again i am sorry for my lack of knowledge i hope i can still ask many more questions in the future.

                          That maybe years a head pendin on the progress AA made we have see the results at Devcon 2016. Even IIS will be supported for many years to come by MS.

                            MAY Be wrong, but seemed IIS is for when you have two or more apps on the same server. IIS will serve up the proper app to the user depending on how they get there.
                            It has been a long time since I used windows server, so a bit out of the loop on it.

                            I do have a site with about 100.000 hits a month and around 25% of thode do log in, some by cell about 10%. No speed issues. This is on Linux though
                            I do have a couple friends deploying at smarterasp an having great success with high volume logins.
                            WILL Be setting up a windows server over the next couple weeks sn a Linux server as well. Can do more testing then.

                              Sure, just like classic ASP you can still use it.

                                I am no expert but here is my 2 cents.
                                We now have 3 servers and 5 projects now running Alpha+IIS and in our testing of IIS it DOES perform better than WAS, for the simple fact that for example we have a VPS with 5 cores and with WAS you see WAS red lining on ONE processor and with IIS you see that load spread over the 5, it is a beautiful thing to watch. This is IIS out of the box, I know there are various options to get multiple instances of WAS running but they all seemed like hacks and hard work, IIS is scalable right out of the box.
                                We have a client that was going to hammer it for a 3-day conference so we dialed up to 8 cores and a boat load more RAM for those 3 days then dialed back when the conference was over. worked for us.
                                I agree that IIS has taken WAY TOO long but we have found Terry at Alpha very helpful. The major down side we have found with IIS it is yet another whole new MASIVE world of knowledge that you need to get on top of. But there is a wealth of IIS knowledge out there so Google search is your friend.
                                I have been lucky that a new project that I am working in that is IIS + AD authentication the client has a very large MS environment and the project manager there is fantastic IIS and AD knowledge so that has helped a lot!
                                Actually… with this client IIS and AD was the deal breaker. Without it they would not have looked at Alpha Anywhere but because of IIS and the AD integration it made it into their short list for the project.
