Tibor17 commented on issue #240: [SUREFIRE-1658] TCP/IP Channel for forked Surefire JVM. Extensions API and SPI. Polymorphism for remote and local process communication. URL: https://github.com/apache/maven-surefire/pull/240#issuecomment-552061820 @rpdai Currently we use `java.nio.channels.AsynchronousServerSocketChannel` but we need to have 2 blocking operations `client.write( bb ).get()` and `client.read( bb ).get()`, and one non-blocking `accept`. The read and write uses another thread in the background. I think using `java.nio.channels.ServerSocketChannel` the number of used threads would be smaller by those two running in the background in JVM. We still need to have another two application threads in both alternatives. So with `AsynchronousServerSocketChannel` there will be 4 threads. And only 2 threads with the `ServerSocketChannel`.
