The ClickHouse database performance has been incrementally improving on newer Linux kernel releases.

👁 MariaDB benchmark with settings of Test: oltp_read_write, Threads: 64. v6.17 3 Sep was the fastest.

MariaDB was showing off some read/write performance improvements when running on Linux 6.17 Git.

👁 PostgreSQL benchmark with settings of Scaling Factor: 1000, Clients: 500, Mode: Read Only. v6.17 3 Sep was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 1000, Clients: 500, Mode: Read Only, Average Latency. v6.17 3 Sep was the fastest.

PostgreSQL is also showing off some incremental performance improvements when running on Linux 6.17 compared to prior kernels for delivering higher throughput and lower latency.

👁 Geometric Mean Of All Test Results benchmark with settings of Result Composite, Linux 6.17 EXT4 Benchmarks. v6.17 3 Sep was the fastest.

The EXT4 performance on Linux 6.17 is looking good as is the Linux 6.17 performance overall from the few systems I have been testing so far with this development kernel. More benchmarks are ongoing in leading up to the Linux 6.17 stable release by late September or early October. A larger file-system comparison will also be coming up given the now-frozen state of upstream Bcachefs and there also being some Btrfs optimizations to explore too for Linux 6.17.
