The numbers for /modsec-off and /modsec-light with multi-worker nginx setup are significantly better than in single-worker mode, but /modsec-full does not show any difference. In the process of investigation it turned out that disabling audit log (by setting SecAuditEngine Off) greatly improves overall performance with OWASP CRS v3.0.0 loaded:

Further investigation showed that in case of SecAuditEngine RelevantOnly only one CPU core (among the set of cores nginx is using according to worker_cpu_affinity) is 100% busy:

With SecAuditEngine Off, all cores that are being used by nginx are constantly busy:

With the recent sources all the nginx workers are busy while benchmarking /modsec-full location (previously only one worker process reached to 100% CPU usage).

Also, turning SecAuditEngine Off does not affect latency && rps anymore.
