Sys whonix being slower in qubes 4.3

So i switched from qubes 4.2 to 4.3 this week and on 4.2 i used sys whonix with 2 bridges and i get around 20-50+mbps and now in 4.3 without any bridges i get around 10-20 mbps at max
does anyone know why it is like this and if there may be a fix

How many times have you run the speed tests? Maybe it was a fluke caused by circuit choices? Alternatively, check CPU usage in sys-whonix while running speedtests, maybe there’s a bottleneck there.

no i tried reloading tor multiple times also on i tried different vms still stays the same

Your guard node can be slow because not all relays have good bandwidth some may have poor bandwidth, which can make your connection slow. However, manually changing guard nodes is not recommended. Tor uses two primary guard nodes by default, as enforced by the consensus parameter guard-n-primary-guards-to-use=2 . This change, introduced via Proposal 291, improves security by reducing reliance on temporary secondary guards due to path restrictions. These primary guards are typically rotated every 2–3 months . If your connection feels extremely slow, you can force a change by deleting the state file in Tor’s data directory, but do so rarely frequent changes increase the risk of selecting a malicious guard and reduce long-term anonymity.

ah thank you
also for some reason if i put mullvad before sys whonix the speed goes from max 20 mbps to 30+ which doesnt make sense it should be slower
