<description>&lt;div data-index=&quot;0&quot; data-line-number=&quot;1&quot; data-line-start=&quot;1&quot; data-line-end=&quot;1&quot; class=&quot;code-line&quot; style=&quot;display: flex; min-height: 1.2rem;&quot;&gt;&lt;div class=&quot;line-content&quot; style=&quot;direction: ltr; flex: 1 1 0%; white-space: pre-wrap; word-break: break-word;&quot;&gt;&lt;span&gt;Our platform is experiencing severe CPU spikes reaching 95% during peak traffic hours (over 15,000 active sessions). &lt;/span&gt;&lt;/div&gt;&lt;/div&gt;&lt;div data-index=&quot;1&quot; data-line-number=&quot;2&quot; data-line-start=&quot;2&quot; data-line-end=&quot;2&quot; class=&quot;code-line&quot; style=&quot;display: flex; min-height: 1.2rem;&quot;&gt;&lt;div class=&quot;line-content&quot; style=&quot;direction: ltr; flex: 1 1 0%; white-space: pre-wrap; word-break: break-word;&quot;&gt;&lt;/div&gt;&lt;/div&gt;&lt;div data-index=&quot;2&quot; data-line-number=&quot;3&quot; data-line-start=&quot;3&quot; data-line-end=&quot;3&quot; class=&quot;code-line&quot; style=&quot;display: flex; min-height: 1.2rem;&quot;&gt;&lt;div class=&quot;line-content&quot; style=&quot;direction: ltr; flex: 1 1 0%; white-space: pre-wrap; word-break: break-word;&quot;&gt;&lt;span&gt;After checking the MySQL slow query log, several complex JOIN queries on large tables are taking between 3 to 6 seconds to complete. &lt;/span&gt;&lt;/div&gt;&lt;/div&gt;&lt;div data-index=&quot;3&quot; data-line-number=&quot;4&quot; data-line-start=&quot;4&quot; data-line-end=&quot;4&quot; class=&quot;code-line&quot; style=&quot;display: flex; min-height: 1.2rem;&quot;&gt;&lt;div class=&quot;line-content&quot; style=&quot;direction: ltr; flex: 1 1 0%; white-space: pre-wrap; word-break: break-word;&quot;&gt;&lt;/div&gt;&lt;/div&gt;&lt;div data-index=&quot;4&quot; data-line-number=&quot;5&quot; data-line-start=&quot;5&quot; data-line-end=&quot;5&quot; class=&quot;code-line&quot; style=&quot;display: flex; min-height: 1.2rem;&quot;&gt;&lt;div class=&quot;line-content&quot; style=&quot;direction: ltr; flex: 1 1 0%; white-space: pre-wrap; word-break: break-word;&quot;&gt;&lt;span&gt;Could a database specialist share the exact production configuration and caching architecture needed to bring query execution down to under 50ms?&lt;/span&gt;&lt;/div&gt;&lt;/div&gt;</description>
