That is significant on modern CPUs as well as on battery life for laptops while finally the issue has been fixed...

While the Open Sound System (OSS) usage hasn't been prevalent on Linux systems in many years, on NetBSD there still is some software making use of the OSS interfaces in not supporting the native NetBSD audio interfaces.
