-## JMeter setup
+## Test setup
 
-SSH into your machine and run the following commands
+Install the Apache HTTP server benchmarking tool (`ab`):
 
 ```console
-$ mkdir jmeter
-$ cd jmeter
-$ wget --quiet https://archive.apache.org/dist/jmeter/binaries/apache-jmeter-5.5.tgz
-$ tar --extract --file apache-jmeter-5.5.tgz

+$ sudo yum install --assumeyes httpd-tools
 ```
 
 ## Running the tests
 
 [`run_enclave.sh`](run_enclave.sh) contains the commands to start the
 nitro enclave. The first argument specifies the number of vCPUs to use
-for the enclave (defaults to `4`). [`run_jmeter.sh`](run_jmeter.sh)
-runs the JMeter test suite and prints the summary of the results.
+for the enclave (defaults to `4`).
 
-The two scripts can be invoked in one line:
+After starting the enclave, run `ab` to benchmark the
+performance. This can be done in one line (with a delay to allow the
+enclave to start):
 
 ```console
-$ sudo ./run_enclave.sh && ./run_jmeter.sh
+$ sudo ./run_enclave.sh && sleep 5; ab -n 10000 -c 100 localhost:8082/busy
 ```
 
 ## Sample results
 
+The following test results were gathered on a c6a.2xlarge instance.
+
 With four vCPUs:
-```
-summary = 12000 in 00:00:42 = 283.7/s Avg: 155 Min: 12 Max: 2707 Err: 0 (0.00%)

-At the moment, there is no significant difference in TPS by increasing
