Hello, While I was trying to diagnose the problem that JMH benchmarks can't be run on a fresh cygwin or WSL environment, https://bugs.openjdk.org/browse/JDK-8305669 I found myself troubled with path issues and slow building speed with a Windows target. Meanwhile the linux target is totally fine.
1. When I pass --with-jmh=build/jmh/jars in WSL configuration, it always fails to find the relative directories (not present on linux configuration). C:\\...\\jdk\\build\\jmh\\jars doesn't work. Only /mnt/c/.../jdk/build/jmh/jars work. Is this a bug? 2. My Windows WSL build is extremely slow. My windows target has almost stalled that it stuck on creating benchmark jar without even progressing to indify. And it seems WSL (Ubuntu) itself is only using 400MB of RAM with almost no CPU usage. However, these problems don't happen for my Linux target builds; meanwhile my cygwin builds are blazingly fast. What could be the cause of this slowness? Curious, Chen Liang
