I just ran a load test against my app. I noticed some very large variability in latency for two identical requests: 3 s vs. 30 s. When I dug into the traces I found the following:

```
|                      | Traced (ms) | Untraced (ms) |
|----------------------+-------------+---------------|
| High-latency Request |         193 |         29948 |
| Low-latency Request  |         305 |          2934 |

```

Here are screen shots for the traces:

**Low overall latency**

**High overall latency**

I cannot make sense of a 10-to-1 difference in runtime performance.

I only see these high-latency requests under load. Could something in my code account for this variability (assuming the same path through the code was followed for both requests)?
