From 47f3bfba814be1a3ab6aa29f13d064ac5687eb2e Mon Sep 17 00:00:00 2001 From: Omkar Kulkarni Date: Wed, 23 Oct 2024 10:50:36 +0200 Subject: [PATCH] tests: settings: Performance test for settings This adds a on target performance test for Settings SS. Using this test performance of the Setting SS + NVS/ZMS backend can be benchmarked. The test repeatedly write 255 settings entries. Each setting entry has a size of 4 bytes, and path length of 16 bytes (excluding the null-terminator). The test has two variants, with and without Bluetooth scan running. This is useful to benchmark performance along with some component of BT subsystem activated. The test could be enhanced in future to include or create combinations of different functionalities running, when agreesive store operations are happening.
