Statistics
With IMQA WPM statistics, you can retrieve previous data of various subjects using periods and conditions for observance and analysis. You can analyze the user data distribution for each performance index along with the user’s environment, or obtain the overall web status and insight.
1. Distribution Analysis
Distribution Analysis allows you to analyze the distribution of user data for each performance metric along with the user experience. After viewing the overall average performance in the Dashboard, you can drill down into specific bins with performance degradation in 30-minute increments.
The IMQA WPM Distribution Analysis page consists of the following:
❶ Timeline ❷ Performance rating graph ❸ User information ❹ Performance heat map
Timeline
You can set the date and time (in 30-minute increments) you want to analyze. When you make changes, Performance Distribution Graph and User Experience will be updated as per your preferences.
❶ Timeline You can change the date and time (in 30-minute increments) you want to analyze. When changes are made, the performance heatmap is updated based on the selected criteria.
❷ Analysis Date Defaults to “Today." You can change the date by clicking [<] [>]. Can select a date up to 30 days ago.
❸ Selected time zone Displays the selected time zone. You can change to a different time zone.
❹ Current time zone Displays the time zone that includes the “current time”.
❺ Legend Color density is displayed in 4 steps according to the number of aggregated data by time zone.
Performance rating graph
Displays the user data distribution for the selected 30 minutes as a histogram. You can analyze User Experience and Performance Heat maps by selecting a bin in the Performance Distribution Graph area.
❶ Performance Metrics You can change the performance metrics to “Rendering Time” and “Response Time" When you change the metric, Performance Distribution Graph and User Information will be updated accordingly.
❷ Histogram The histogram shows the class on the horizontal axis and the frequency on the vertical axis. It creates classes by setting several sectors for aggregated data and expresses the frequency with the number of data belonging to each class. The histogram is useful for understanding or comparing the frequency status of an entire population.
| index | X-axis | Class | Y-axis |
|---|---|---|---|
Rendering Time | Rendering time(ms) | 0 ~ 5,000ms | Number of collected data |
Response Time | Response time(ms) | 0 ~ 10,000ms | Number of collected data |
❸ 50% baseline Displays the average performance baseline. Showing the median of the overall data distribution, it is useful for understanding overall performance. A baseline closer to zero indicates faster performance.
❹ 95% baseline Displays the baseline of bottom 5% performance. Shows where the bottom 5% of the overall data distribution begins, useful for identifying the lowest performing data. A baseline closer to zero indicates faster performance..
❺ Analyzable Bins You can select bins separated by a baseline to drill down into performance data. Filter user information by the selected bin and display a performance heatmap. You’ll see up to three bins. Bins can overlap because they are divided based on the location of the data. In this case, a bin with higher % is shown.
Bin 1: 0th to < 50th percentile in the total data distribution
Bin 2: 50th to < 95th percentile in the total data distribution
Bin 3: ≥ 95th percentile in the total data distribution
You can check the performance environment of the app user by referring to the performance rating graph. If most of the users are distributed in the threshold range, we can see that the app is used smoothly. If they are distributed widely, it means that the app is not optimized for various user environments. You can use this information as an improvement index to set the target performance of the web browser application
User information
The information is displayed for the bottom 5% section of basic performance and the selected one-day user environment is displayed in percentage. This information is updated when a section is changed in the performance rating graph area.
Browser: Displays users’ browsers aggregated over the selected section.
OS: Displays the OS of the user aggregated from the selected section.
Page: Displays the page of the user data aggregated from the selected section.
User information is displayed based on the user’s User-Agent information when a user visits the website. IMQA WPM categorizes users by the OS and browser they use. OSs are typically categorized into Windows, macOS, Android, iOS, and Linux.
Browsers are generally categorized into Chrome, Safari, Microsoft Edge, Firefox, and Samsung Browser. An unspecified OS or browser may be labeled as “Unknown."
Performance heat map
Displays the performance heat map that is related to the selected performance index standard. You can check the heat map for rendering time. For more information on the heat map by performance index, refer to “IMQA WPM User Guide > 4.6. Performance heat map”.
Rendering Time
You can view page load times measured on individual pages or SPA-based web browser applications. If you click a desired cell in the heat map area or select a section by dragging the mouse, the “Detailed performance analysis” pop-up window will be displayed.
Rendering Time: Calculates the loading time taken until the HTML page fires an onload event or a DOM change as a bin.
Legend: Displayed in red if the section is more than the threshold, and blue if it is less than the threshold. Color density is displayed in 4 steps according to the ratio of the data collected in the same-time axis.
◼︎ More than the threshold ◼︎ Less than the threshold
Response time
You can see the HTTP response time requested by the page. If you click a desired cell in the heat map area or select a section by dragging the mouse, the “Detailed performance analysis” pop-up window will be displayed.
Response time: Calculates the HTTP response time as a section.
Legend: If the collected HTTP is in 4xx, 5xx status codes, it will be displayed in red. Otherwise, it will be displayed in blue. Color density is displayed in 4 steps according to the ratio of the data collected in the same-time axis.
◼︎ 4xx, 5xx status codes ◼︎ etc.
2. Performance analysis
Performance Analytics displays the number of website accesses & visits and each performance metric as a time-series graph, and you can change bins to see where performance has dropped and how it is fluctuating from a macro perspective.
30 min: Shows performance for the last 30 minutes at 1-min intervals.
1 hour: Shows performance for the 1 hour at 1-min intervals.
3 hours: Shows performance for the last 3 hours at 1-min intervals.
12 hours: Shows performance for the last 12 hours at 1-min intervals.
24 hours: Shows performance for the last 24 hours at 1-min intervals.
3. Screen analysis
Screen Analytics displays the visit rate and issue rate, as well as the bottom 5% and average for each performance metric for a page visited by website users. You can change bins to see at a glance performance degradation that occurred per page. Pages are sorted by the highest visit rate, and you can jump to “Performance Analytics by Page” by clicking the screen card.
4. User Statistics
You can check a user’s previous data on websige usage within a specific period from the User Statistics. You can inquire by period and conditions and get insights regarding website users through statistics by subject. You can check the status or identify patterns from a macroscopic perspective.
