See: Bug 48889 - Wrong response time with mode=Statistical and num_sample_threshold > 1 https://issues.apache.org/bugzilla/show_bug.cgi?id=48889 The only work-round (until the next version is released) is to use a different batching mode. > > Best regards, > > > > > Jörg > > > > > > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
