But you might also increase the JVM memory used for running pulsar-perf. - Sijie On Sat, Jul 3, 2021 at 11:55 AM 何宗霖 <hezonglin1...@qq.com.invalid> wrote: > > Dear, > I use the pulsar perf to test the service by the > command: pulsar-perf produce topic1 -n 1 -t 10 -r 1000000, but the log shows > that the Throughtput Produced just below 10000, i need to test the service > by higher message rate, how can i do ?
