10/11/2023, 8:47 AMI’m using wiremock for performance testing and I see a degradation in the wiremock performance. I’m using the standalone version with those parameters:
java -jar wiremock-standalone-3.2.0.jar --no-request-journal --disable-request-logging --async-response-enabled=true --container-threads=100
Any recommendations for optimalisation?
