I can comment on the T2-based systems- they have limited floating point capabilities compared to the rest of the multi-core part of the T2 chips, so anything requiring heavy floating point cpu would be not nearly as fast as the rest of the cpu capabilities. This was most evident when doing compressed RMAN backups, where CPU usage would be far higher (and performance far slower) than expected. Turning off compression helped a great deal.

After an evaluation we found that T2 processor servers (e.g. T5240) wouldn't be a good choice for such environment. So we are planning to replace our 3-node clustered environment with 2-node M4000 servers. I haven't heard any issues with M4000 server but would like to check with you in case if there is one.
