From ea2ea8ef28b6a2207ec00bafaf42d428612d69eb Mon Sep 17 00:00:00 2001 From: Giteabot Date: Sun, 21 Apr 2024 08:50:50 +0800 Subject: [PATCH] Fix package list performance (#30520) (#30616) Backport #30520 by @KN4CK3R Fixes #28255 The new query uses the id field to sort by "newer". This most not be correct (usually it is) but it's faster (see #28255). If someone has a better idea, please propose changes.
