[Aptitude-devel] Bug#822329: aptitude: Hold Package and Upgrade Package slow

[Christian Klein]

Package: aptitude
Version: 0.8-1
Severity: important

Since upgrading to 0.8-1, standard operations in aptitude are really slow.
When requesting an upgrade of a package (+) or holding (h) a package, or
downgrading a package, aptitude takes several seconds to respond (with 100% cpu
usage). While I know that this annoying behavior happens if a package
dependency is broken, I didn't encounter it for a normal upgrade/hold operation
until upgrading to 0.8-1. A downgrade to 0.7.5-3 in testing immediately brought
back the old behaviour (annoyingly slow only if there are broken packages
around), so I'm pretty sure that this was newly introduced in some version
after 0.7.5-3, probably with the new 0.8 release. Since I got a pretty fast
Skylake PC i really wonder why aptitude needs several seconds to complete such
operations.
