I have a theory for why this happens.
In this whole world, only Nokia ASIC can do HQoS. All other ASIC must do HQoS in software.
Now as TM try to nest their configuration deeper and deeper, it gets progressively more expensive to perform HQoS and the CPU is pegged.
For DPDK in general, which means all telco grade equipment, each stream will be processed by different core.
In your case by using a IDM, you are basically doing multiple streams, hence on TM side, multiple CPU core is involved and you can saturate your subscribed speed.
How much each core can do HQoS is kind of a trade secret that only vendor and customer knows. Juniper MX Trio 4 ASIC for example, will be pegged at around 5Gbps.
I use Cisco ASR for another example. They quote aggregated bandwidth due to this same reason. Want single stream to max out the port speed? Buy their Silicon One ASIC.
You know what, I try all speedtest server, only Digi at Seri Kembangan can saturate my 2Gbps In this whole world, only Nokia ASIC can do HQoS. All other ASIC must do HQoS in software.

All other server give crap speed
What do you think?
ibse02.mc give 7ms before
ibse02.rsh now 12ms, that 5ms increase, even stay in Seremban Town, ping make I stay in Kampung,
