# `Slow Queries` Panel - Example

------------------------------------------------------------------------------
In the `Slow Queries` panel, it is important to pay close attention to the `Latency`, `Process Keys`, and `Total Keys` of the SQL statements.

For instance, in this example, the `Latency` is 56.0 seconds, the `Process Keys` count is 28, and the `Total Keys` count is 29. These metrics relate to a single execution of an SQL statement. Therefore, it is also crucial to review the `# Exec` statistic in the `SQL Statements` panel. This allows us to deduce that the SQL statement with the highest product of `Total Keys` and `# Exec` has the most significant impact on the TiKV layer.

Unlike the `SQL Statements` panel, the `Slow Queries` panel does not face memory overflow issues arising from the accumulation of excessive historical SQL data.
