Metrics (Intel) - phoronix/java-gradle-perfThis test runs Java software project builds using the Gradle build system. It is intended to give developers an idea as to the build performance for development activities and build servers.

Overall, the workload has many short-lived processes (237 in 24 seconds) and is On_CPU 39% of the time. A relatively high percentage of voluntary context switches (>90%) means processes finishing quickly to yield. The IPC is somewhat lower, in part with many front-end stalls and speculative misses.
Metrics (AMD) - phoronix/java-gradle-perfsh - pid 12075 On_CPU 0.312 On_Core 4.989 IPC 0.925 FrontCyc 0.146 (14.6%) BackCyc 0.139 (13.9%) Elapsed 24.86 Procs 327 Maxrss 543K Minflt 349112 Majflt 0 Inblock 0 Oublock 18432 Msgsnd 0 Msgrcv 0 Nsignals 0 Nvcsw 167598 (93.1%) Nivcsw 12406 Utime 118.175617 Stime 5.843946 Start 67266.09 Finish 67290.95
AMD has twice as many cores and shows slightly lower On_CPU utilization and IPC.

Adding total On_CPU times for all cores shows the slightly chaotic nature of many short-lived small processes.
About this graph
This also then shows up separating out the cores.
The overall IPC is approximately 1.0 but varies by different short sections of processes run.
About this graph
Front end stalls and poor speculation are the largest issues with back end stalls not a big issue.
Next steps: Understand causes for speculative misses.
