tomaswolf opened a new issue, #293: URL: https://github.com/apache/mina-sshd/issues/293
Looking through the GitHub build logs, there seems to be a problem with two tests on Linux, with the NIO2 or MINA transport back-ends. They show very poor performance: **org.apache.sshd.sftp.client.SftpTransferTest** ``` Build NIO2 MINA Netty ubuntu, java 8 ~300s ~300s ~70s ubuntu, java 11 ~300s ~300s ~50s ubuntu, java 17 ~300s ~300s ~50s windows, java 8 ~62s ~67s ~66s windows, java 11 ~49s ~49s ~43s windows, java 17 ~43s ~44s ~45s ``` **org.apache.sshd.scp.client.ScpTest** ``` Build NIO2 MINA Netty ubuntu, java 8 ~19s ~19s ~11s ubuntu, java 11 ~19s ~19s ~11s ubuntu, java 17 ~19s ~19s ~11s windows, java 8 ~12s ~12s ~12s windows, java 11 ~12s ~12s ~12s windows, java 17 ~12s ~12s ~12s ``` These are the only tests for which I see such discrepancies. It looks like the code is doing something that doesn't play well with NIO2 or MINA on Linux. It's not a new problem either; I could find this pattern also in the [build logs of 2022-10-25](https://github.com/apache/mina-sshd/actions/runs/3318464369/jobs/5482485034) (commit 7ad3eadef) and also in even older builds. Though e.g. in a [build from 2022-09-20](https://github.com/apache/mina-sshd/actions/runs/3089979040/jobs/4998289149) the differences are smaller (but still there; 120s instead of 300s, and 15s instead of 19s). The windows times and the Linux/Netty times appear to be about normal and are what I also see for NIO2 or MINA when building locally on OS X: 12s for ScpTest and about a minute for the SftpTransferTest.
