This will allow you to achieve the best possible performance in the quickest amount of time in a production system.But I would prefer applying indexing properly in the database in the first place, because of the following two reasons: Well, some could argue whether implementing proper indexing should be the first step in the performance optimization process for a database. Let us start our optimization mission in a step-by-step process: Step 1: Apply proper indexing in the table columns in the database So, you need to review and optimize your data access/manipulation routines for improving the overall application performance. When a database based application performs slowly, there is a 90% probability that the data access routines of that application are not optimized, or not written in the best possible way. We have a database to optimize, let's start! ![]() But, optimization scopes that fall into a DBA's area are out of scope for these articles. Database Administrators (DBAs) also have a great role to play in optimizing and tuning database performance. That is, as a developer, I'll focus on the issues that you need to follow to make sure that you have done everything that you could do to optimize the data access code you have written or you are going to write in future. But, most of the optimization techniques are roughly the same for other database platforms.Īlso, the optimization techniques I am going to discuss are applicable for software application developers only. Please note that the primary focus of this series of articles is "data access performance optimization in transactional (OLTP) SQL Server databases". I just hope this might enable you to optimize your data access routines in existing systems, or to develop data access routines in an optimized way in your future projects. I want to help you do this by sharing my data access optimization experiences and findings with you in this series of articles. If you are part of this story, you must have not written the data access routines in your application in the best possible way, and it's time to optimize those now. I know why such situations take place, and I can tell you what to do to overcome this. Almost every developer, including me, has taken part in the story sometime in his/her development life. This is the same old story for thousands of application projects developed worldwide. The testing team performed a test on the production site, and they found that the order submission process was taking 5 long minutes to complete, whereas it used to take only 2/3 seconds to complete in the test site before production launch." Looking into the database, you find that the database tables have grown large in size and some of them were containing hundreds of thousands of rows. Soon you discover that the production database was performing extremely slowly when the application was trying to access/update data. The client claimed that they started losing users. E-mails started to arrive from the client complaining that the site is performing too slowly (some of them ware angry mails). As the number of users in the site started growing at a rapid rate day by day, problems started occurring. Your client, management, team and you - everybody is happy. You have a pretty satisfied client so far as the site was able to attract thousands of users to register and use the site within a small amount of time. Unfortunately, while the link *says* 4.1.4.116, it *actually* points to the current version, 4.1.6.118." It's been months since you and your team have developed and deployed a site successfully in the internet. Thank you also for trying to provide a link to the old WMO so that I could try reverting. I am running Windows 7 Home Premium 64-bit. It often gives "not enough timers" error messages. The new one only works manually, and sometimes not even then. The previous version worked automatically to manage RAM usage. My concern is that the new version is not working as well as the previous version did. Unfortunately, it does not address my concerns. The following link is to download version 4.1.4 (portable version) Please open the Task Manager and check which process is taking up more memory. On my computer (latest Windows 11), version 4.1.6 uses 5.3-6 MB of memory, and version 4.1.4 uses 4.5-5.0 MB of memory. Yes, Wise Memory Optimizer v4.1.6 uses more memory than v4.1.4 because 4.1.4 is only a 32-bit version, while 4.1.6 has 32-bit and 64-bit versions.
