The Stargate digital audio workstation software was observing slightly better performance with Cache Aware Scheduling.

👁 TigerBeetle benchmark with settings of Clients: 8. Cache Aware Scheduling was the fastest.

👁 TigerBeetle benchmark with settings of Clients: 16. Cache Aware Scheduling was the fastest.

TigerBeetle was also seeing slightly better performance when running multiple clients.

👁 Valkey benchmark with settings of Test: GET, Parallel Connections: 50. Cache Aware Scheduling was the fastest.

One of the largest performance boosts observed out of employing Cache Aware Scheduling was with the Valkey fork of Redis when testing GET operations.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 100, Mode: Read Write. CAS Disabled was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 100, Mode: Read Write, Average Latency. CAS Disabled was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 250, Mode: Read Write. Cache Aware Scheduling was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 250, Mode: Read Write, Average Latency. Cache Aware Scheduling was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 500, Mode: Read Write. Cache Aware Scheduling was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 500, Mode: Read Write, Average Latency. Cache Aware Scheduling was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 800, Mode: Read Write. Cache Aware Scheduling was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 800, Mode: Read Write, Average Latency. Cache Aware Scheduling was the fastest.

The PostgreSQL database server also showed some nice wins on this AMD Zen 5 system out of Cache Aware Scheduling. When dealing with enough concurrent clients there were some rather nice wins with Cache Aware Scheduling that is expected to be merged for Linux 7.2.
