Its is lower.
With nema 23 it was 1revolution -5mm move (6000mm/min)
With nema 34 it is 1rev -15mm move . (7000mm/min)travel speed.
The problem is that i cant get feed over 7000mm/min,because the motor stalls.
How is it possbile,where is the mistake ?

Hello. Im quite a new in this field and my english is not so good, sorry about that But i hope i can get some knowledge here.

My setup
I have three axsis woodcutting machine. 1.2m x1.2m
All axes are using Nema 23 3nM 4.2 Amps motors that are directli connected to leadscrew  1 rev=5mm.
Im using  Leadshine DM556 Digital Stepper Driver Max 50 VDC with 5.6A drivers and Ethernet Smoothstepper.
Power is connected with two 48v 5A supplyes  to din rail = 10 A
Everything worked well , i got 6000mm/min feed.

Now i made changes. I replaced nema 23 with nema 34 8.5nM 5A to axis x . With 1/3 gear to leadscrew.
And there is the problem, i will get only 7000mm/min feed. So it is only 1000mm/min more than with nema 23 and no gear.
If feed is more than 7000mm/min then the motor stalls.
I changed pulse width, microsteps, but i cant get higher results
Can someone help me? What to do? What to check
