Branch: refs/heads/master Home: https://github.com/Checkmk/checkmk Commit: 49d409ee2c1e93004c0291a50b5f66e25a933c0d https://github.com/Checkmk/checkmk/commit/49d409ee2c1e93004c0291a50b5f66e25… Author: Lars Michelsen <lm(a)checkmk.com> Date: 2024-07-23 (Tue, 23 Jul 2024) Changed paths: M cmk/gui/wsgi/blueprints/checkmk.py M cmk/gui/wsgi/blueprints/rest_api.py A cmk/gui/wsgi/wsgi_import.py M omd/packages/check_mk/skel/etc/check_mk/apache.conf Log Message: ----------- Improve UI initialization performance It was observed that the initialization of the cmk.gui code executed main_modules.load_plugins() twice. This was due to the fact that the the UI and REST API blueprints were calling that function. The research on this issue revealed that the Apache python environment initialization, which is triggered through the mod_wsgi directive WSGIImportScript was not triggering the main_modules loading as intended. This commit introduces a new import script that only cares about the main modules imports. Since it is executed by mod_wsgi before requests can be answered by apache processes, it should not slow down initial requests anymore. Of course, the initial Apache process will need a bit more time to be ready to handle requests now. But even this should be better since the imports are done during startup and not during the first request.
