👁 MariaDB benchmark with settings of Test: oltp_update_index, Threads: 128. 6.16.2 was the fastest.

The MariaDB database server also showed much better performance on Linux 6.6 and later. Though Linux 6.17 Git clocked in slower than Linux 6.16/6.12 as a possible regression but still far better off than where it was on Linux 5.15/6.1 kernels.

👁 Flexible IO Tester benchmark with settings of Type: Random Read, Engine: IO_uring, Direct: No, Block Size: 4KB, Job Count: 32, Disk Target: Default Test Directory. 6.16.2 was the fastest.

👁 Flexible IO Tester benchmark with settings of Type: Random Read, Engine: IO_uring, Direct: Yes, Block Size: 4KB, Job Count: 32, Disk Target: Default Test Directory. 6.16.2 was the fastest.

👁 Flexible IO Tester benchmark with settings of Type: Random Write, Engine: IO_uring, Direct: No, Block Size: 4KB, Job Count: 32, Disk Target: Default Test Directory. 6.16.2 was the fastest.

The FIO benchmark showed some of the raw I/O improvements on the newer versions of the Linux kernel for this AMD EPYC dual socket server.
