Benchmark details

All benchmarks on the physical machines, against external database, for 2 minutes. Npgsql used perfhacks branch, bec42649e324bd39331b33e30d6800d45a1818f8.

Machines are physical Intel Xeon E5-1650 @ 3.50Ghz, 6 physical cores, 12 threads. 32GB DDR4.

Running the database-only tests

Linux JDBC:

1. ssh to aspnet@asp-perf-lin
2. If you need to build, cd to ~/roji/jdbc, the Dockerfile and benchmarking app are here.
3. docker run -it java
4. /JdbcPerfTest/out/production
5. java -cp /JdbcPerfTest/out/production/jdbc-perf-test:../../lib/HikariCP-2.7.6.jar:../../lib/slf4j-api-1.7.25.jar:../../lib/p ostgresql-42.2.1.jar com.company.Main "jdbc:postgresql://10.0.0.103/hello_world?user=benchmarkdbuser&password=****"
