As far as I can tell, siege&#x2F;vegeta&#x2F;ab&#x2F;boom&#x2F;wrk are all affected by Coordinated Omission, which makes their results of little value. The only tool I&#x27;m aware of doing this properly is wrk2. I&#x27;m not sure about the distributed tools, free JMeter or hosted like gatling.io and blitz.io, but I&#x27;m fairly certain that they all suffer from the same problem.<p>If you&#x27;re reaching for a tool like that and can code in Go, implementing a correct one is very easy (~200 loc): just spin up new goroutines for each request at a regular interval.
