Could you also provide some information on your LDG machine - its

really matter as long as it is same across runs)
So I'm looking at logs at LDG side which is a 4th Generation EPYC system
with 192CPUs running the repro on baremetal and I see:
[20250502.061627] [INFO] STARTING TEST
[20250502.061627] [INFO] 768 VU
...
Vuser 2:VU 2 : Assigning WID=1 based on VU count 768, Warehouses = 24 (1 out of 1)
Vuser 2:Processing 1000000000000 transactions with output suppressed...
...
Now that is equal to 4 * 192CPUs that my LDG has which means I might
need to match the same configuration as your LDG to mimic your exact
scenario.
768VU each processing 1000000000000 transactions sent to a 16vCPU
SUT instance seems like a highly overloaded (and unrealistic) scenario
but perhaps your LDG is also a similar 16vCPU instance which caps the
VU at 64?
Currently doing a trial run, staring at logs to see what I need to
adjust based on the errors. I'll adjust the LDG based on your comments
and try to reproduce the scenario over the weekend.
