I'm currently working on a TREP 3 migration.
I tried to benchmark TREP 2 against different TREP 3 configurations.
I would like to know if our results are consistent with your experiences
The latest official performance results on TREP 3.0.2 can be found here (Gen8/IvyBridge).
We are also planning to publish new results in Q1 (on Gen10/Skylake hardware).
In order for us to better understand what you are seeing, please create a support case with the complete test details (platform, versions, config, # of item/writer threads, etc). on My Refinitiv Suppport choose product "TREP".
