Recently I noticed that Cubase became very slow when loading: at “Initializing: Global Settings” step.
Closing Cubase is slow.
Loading Preferences presets list is also slow (Cubase is freezing for ~10 seconds).
After investigating, I noticed that UserPreferences.xml size is ~90MB, which seems to be root cause of this.
Most of the file size is occupied by “LogPreset@” and “LogPresetA” bin enties which are serialized into this XML file, even though the name suggests that it probably just should be used for logging.
I tried manually deleting these binary entries in XML (and after the file size becomes ~200KB, Cubase starts fast), but the log entries are re-serialized again when Cubase is (slowly!) closing.
The “offensive” binary entries are serialized under AutoSavers\PMidiSetup\Filters.
Below is the screenshot of the location (I deleted binary entries contents) in this example.
Any suggestions what I can do to fix this?
