Improve Performance vs Optimize Performance || Power BI || Belayet Hossain

The terms "𝗶𝗺𝗽𝗿𝗼𝘃𝗲 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲" 𝗮𝗻𝗱 "𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗲 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲" in Power BI are closely related, but they have slightly different connotations:

𝟏. 𝐈𝐦𝐩𝐫𝐨𝐯𝐞 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞

𝗗𝗲𝗳𝗶𝗻𝗶𝘁𝗶𝗼𝗻: "Improve performance" refers to making changes or adjustments to increase the efficiency, speed, and responsiveness of a Power BI report or dashboard. The focus is on enhancing the current state, particularly if there are noticeable performance issues.

𝗖𝗼𝗻𝘁𝗲𝘅𝘁: This term is often used when a Power BI report is underperforming or when users are experiencing delays, slow load times, or lag. The goal is to make the report work better than it currently does.

𝗘𝘅𝗮𝗺𝗽𝗹𝗲𝘀:

① Reducing the load time of a report by removing unnecessary columns.

② Decreasing the time it takes for a visual to render by simplifying a complex DAX formula.

③ Making incremental improvements based on user feedback or performance monitoring.

𝟐. 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐞 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞

𝗗𝗲𝗳𝗶𝗻𝗶𝘁𝗶𝗼𝗻: "Optimize performance" refers to the process of fine-tuning and refining a Power BI report or dashboard to achieve the best possible performance. The focus is on maximizing efficiency and effectiveness, even if the report is already performing well.

𝗖𝗼𝗻𝘁𝗲𝘅𝘁: This term is often used when there is a need to ensure that a Power BI report is running at its peak performance, regardless of whether there are noticeable issues. Optimization is about achieving the best possible performance, not just improving upon problems.

𝗘𝘅𝗮𝗺𝗽𝗹𝗲𝘀:

① Redesigning the data model to minimize memory usage and improve processing speed.

② Implementing best practices for DAX calculations to ensure they run as efficiently as possible.

③ Using Power BI Premium features, such as aggregations or incremental refresh, to handle large datasets more effectively.

𝐊𝐞𝐲 𝐃𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬:

𝗦𝗰𝗼𝗽𝗲: "Improve performance" is often reactive, addressing specific issues to make things better, while "optimize performance" is proactive, seeking to achieve the highest possible level of performance.

𝗔𝗽𝗽𝗿𝗼𝗮𝗰𝗵: Improvement focuses on addressing existing pain points, whereas optimization involves refining and enhancing an already well-functioning system to reach optimal efficiency.

𝗚𝗼𝗮𝗹: The goal of improving performance is to remove bottlenecks and enhance the user experience, while the goal of optimization is to push the boundaries of what the system can achieve in terms of speed, responsiveness, and resource usage.

In summary, "𝗶𝗺𝗽𝗿𝗼𝘃𝗶𝗻𝗴 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲" is about making things better, especially when there are problems, while "𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗶𝗻𝗴 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲" is about achieving the best possible results, even if things are already functioning well.
