Hi,

A couple of Oracle (11.2.0.4 and 19) on AIX (7.2) questions:

Does anyone have any input on whether to use medium pages or large pages on AIX in relation to performance? I'm primarily concerned about performance - especially when the server is stressed.

Does anyone have any input about using SMT2/4/8 usage - my slob testing has seen slightly better throughput with SMT4 over SMT2 (SMT4 vs SMT8 was the same) but my testing has been limited to this point and is far from conclusive.

Neil Chandler.
