Package: neverball Version: 1.6.0-8 Severity: important Neverball automatically saves a replay of the latest run on disk while playing. In the Debian package, the binary constantly calls fsync() on this file, which very seriously degrades performance. If the issue is not obvious when trying to reproduce, try on a machine with as slow a spinning disk as possible.
This is likely a libphysfs issue. Neverball code contains no direct fsync() calls. Neverball upstream has changed the default filesystem backend to be stdio instead of libphysfs, and current upstream code (with no physfs) does not display the problem. In case this depends on precise libphysfs version, seen with libphysfs1 3.0.1-2 on AMD64.
