+## Summary
+
+- Memory usage has increased since 1.0
+- Number of events being processed has increased a bit, therefore so has the average time.
+- CPU and TTR seem to have stayed about the same.
+- One of the CPU charts for the final test was not being calculated properly.

+### Scale HTTP Matches
+
+**Results for the first match**:
+
+```text
+Running 30s test @ http://cafe.example.com
+  2 threads and 10 connections
+  Thread Stats   Avg      Stdev     Max   +/- Stdev
+    Latency    25.09ms   57.91ms 693.45ms   97.96%
+    Req/Sec   284.70     24.62   330.00     84.30%
+  16710 requests in 30.01s, 5.91MB read
+Requests/sec:    556.84
+Transfer/sec:    201.74KB
+```
+
+**Results for the last match**:
+
+```text
+Running 30s test @ http://cafe.example.com
+  2 threads and 10 connections
+  Thread Stats   Avg      Stdev     Max   +/- Stdev
+    Latency    17.63ms    1.93ms  56.53ms   86.77%
+    Req/Sec   284.44     18.22   323.00     74.29%
+  17025 requests in 30.10s, 6.02MB read
+Requests/sec:    565.66
+Transfer/sec:    204.94KB
+```
+
+**Findings**:
+
+- There's not a noticeable difference between the response times for the first match and last match. In
+fact, the latency of the last match is slightly lower than the latency of the first match.
+
+## Future Improvements
+
+- Check that the statuses of the Gateway API resources are updated after each scaling event.
+- Measure the time it takes for NGF to update the status of the Gateway API resources after creating or updating the resources.
+- Record the reload time distributions per bucket after each test.
