I am looking forward to share my thoughts on ‘Reinventing Performance Testing’ at the imPACt performance and capacity conference by CMG held on November 7-10, 2016 in La Jolla, CA. Sometimes it even lead to conclusions like “performance testing hitting the wall” just because load generation may be a challenge.
