Class FinalizeConnection

java.lang.Object

org.postgresql.benchmark.connection.FinalizeConnection

Direct Known Subclasses:

FinalizeConnection_jmhType_B1

public class FinalizeConnection
extends Object

Tests the time and memory required to create a connection. Note: due to TCP socket's turning into TIME_WAIT state on close, it is rather hard to test lots of connection creations, so only 50 iterations are performed.

To run this and other benchmarks (you can run the class from within IDE):

mvn package && java -classpath postgresql-driver.jar:target/benchmarks.jar -Duser=postgres -Dpassword=postgres -Dport=5433 -wi 10 -i 10 -f 1

To run with profiling:

java -classpath postgresql-driver.jar:target/benchmarks.jar -prof gc -f 1 -wi 10 -i 10
