Debian APT Performance Is Becoming Much Better For Incremental Updates

Written by Michael Larabel in Desktop on 26 December 2015 at 02:30 PM EST. 18 Comments
If using APT with PDiff enabled for package diffs to do incremental updates, the latest code should now be much faster.

Ubuntu/Debian developer Julian Andres Klode has made some improvements this week to significantly increase the speed of incremental updates with APT. His optimizations have yielded apt-get being around 10x faster than the older code. These improvements also make APT with PDiff now faster than the default, non-incremental behavior.

Beyond the improvements that landed this week, Julian is still exploring other areas for improving APT update performance. More details via this blog post.
