## 2018-01-25
- Run another round of tests on DSpace Test with jmeter after changing Tomcat's `minSpareThreads` to 20 (default is 10) and `acceptorThreadCount` to 2 (default is 1):
```
$ ./jmeter -n -t ~/dspace-performance-test/DSpacePerfTest-dspacetest.cgiar.org.jmx -l ~/dspace-performance-test/2018-01-25-linode5451120-tomcat-threads.jtl -j ~/dspace-performance-test/2018-01-25-linode5451120-tomcat-threads.log

```
- I changed the parameters back to the baseline ones and switched the Tomcat JVM garbage collector to G1GC and re-ran the tests
- JVM options for Tomcat changed from `-Xms3072m -Xmx3072m -XX:+UseConcMarkSweepGC` to `-Xms3072m -Xmx3072m -XX:+UseG1GC -XX:+PerfDisableSharedMem`
```
