<p>This plugin measures changes in WordPress memory usage as you activate and deactivate plugins. Here's how it works:</p> |
| 158 |
<ol> |
| 159 |
<li>It records the current memory usage of WordPress.</li> |
| 160 |
<li>When you activate or deactivate a plugin, it measures the memory usage again.</li> |
| 161 |
<li>The difference between these measurements gives an estimate of the plugin's memory impact.</li> |
| 162 |
<li>This process is repeated each time you toggle a plugin.</li> |
| 163 |
</ol> |
| 164 |
<p>Note: These measurements are estimates and may vary. Factors like caching, other active plugins, and WordPress itself can influence memory usage. For the most accurate results, consider testing in a controlled environment.</p> |
| 165 |
<p>To begin, try activating or deactivating plugins using the buttons provided. The memory usage history will appear here.</p>| |
