For me. 3.5.10 illustrates a drop from 27K to 18K. See below: 27,052: 3.4.6 24,392: 3.4.6 Again 18,429: 3.5.10 15,993: 3.6.3, digest.enabled=true 16,159: 3.6.3, *digest.enabled=false* 15,943: 3.7.1 16,805: 3.8.0, digest.enabled=true: 16,682: 3.8.0: digest.enabled=false 16,370: 3.8.0 NullMetricsProvider, *digest.enabled=false*
I re-ran the 3.4.6 benchmark and got a reduced result for some reason: 24,392. However that value still exceeds the performance of subsequent releases. Admittedly, this is not a super scientific result set: I'm running 1 node ensemble and the client on the same host. I would love some thirdparty confirmation of my results for sure.
