Typical Feed Rate for PLA?

Typical Feed Rate for PLA?

I've just made a new printer with a Mosquito with 0.4mm CHT nozzle, a Voron silicon sock 50W bond tech heater and a 300C thermistor.

The feed rate seems like it could be a bit slow. It's probably half of what I'd expect. I'm printing 1.75 PLA at 210c with a Bondtech LGX Lite extruder direct drive. The controller is a Duet 3 mini 5+

The feed rate is around 300 mm/min (5 mm/s) which if I'm correct is about half of the advertised flow rate (about 10mm3/s maybe)

What should I expect to be getting? If this is slow, what can I do to diagnose the issue?
