Michael Semb Wever commented on CASSANDRA-16079: ------------------------------------------------ [~paulo], I've confirmed with this and this CI build that it is related to the ring_delay addition. If it is not quick+easy to fix, and because this ticket is blocking our last {{4.0-alpha}} ticket 13701, can be push it out to a separate follow-up ticket? > Improve dtest runtime > --------------------- > > Key: CASSANDRA-16079 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16079 > Project: Cassandra > Issue Type: Improvement > Components: CI > Reporter: Adam Holmberg > Assignee: Michael Semb Wever > Priority: Normal > Fix For: 4.0-beta > > Attachments: Screenshot 2020-09-19 at 12.32.21.png > > > A recent ticket, CASSANDRA-13701, changed the way dtests run, resulting in a > [30% increase in run > time|https://www.mail-archive.com/dev@cassandra.apache.org/msg15606.html]. > While that change was accepted, we wanted to spin out a ticket to optimize > dtests in an attempt to gain back some of that runtime. > At this time we don't have concrete improvements in mind, so the first order > of this ticket will be to analyze the state of things currently, and try to > ascertain some valuable optimizations.
