Issue

I'm getting download speeds of 30-50 Mbit/s on a 100 Mbit/s connection. I have tried the proposed workarounds in issues #10248 and #9715, but they have had no effect on this issue whatsoever.

Hardware:
AMD 7950X
Asus TUF X670E Plus
64 GB RAM
WD SN850X 2TB

Steam Beta Branch: Steam Beta Update
Steam Version: 1731112063
Steam Client Build Date: Sat, Nov 9 01:37 UTC -08:00
Steam Web Build Date: Sat, Nov 9 01:55 UTC -08:00
Steam API Version: SteamClient021

tldr workarounds tried:

changing steam client branch had no effect
changing download region had no effect
changing router's DNS server between ISP default and 1.1.1.1 had no effect
steam_dev.cfg tweaks did not work (but see below)
dnsmasq config had no effect
not locked to only one server, so using /etc/hosts to block unwanted servers (see https://github.com/ValveSoftware/steam-for-linux/issues/9715#issuecomment-2425357737) is pointless

I still have a completely separate Windows (11, 22H2) installation on the same system (not dual boot; I boot from UEFI if I need to use Windows). On Windows I don't have this issue, downloads are always on 100% of bandwidth.

I'm not locked to only one download server (without any tweaks):
dl_sources_default

The proposed HTTP2/download server tweaks with steam_dev.cfg do allow more connections, but it has absolutely no effect on my actual download speed:
dl_sources

Steps for reproducing this issue:

Install Arch Linux
Install Steam from the Arch official (multilib) repositories
Launch Steam
Try to download a game

Update

I double-checked, and a bunch of packages were updated during the day/evening (I did pacman -Syyu in the morning). This along with a reboot seems to have solved this, at least for now.

I'm attaching the list of updated packages here, in case it helps in pinpointing the root cause.

I'm still connecting to the same download servers as before, but now the download rate is steady and at full bandwidth. Before, it was bursty, constantly jumping up and down.

I also confirmed that the stable client (v. 1730853027) now also maintains full bandwidth.
