Hello again,
I noticed this now several times: When i restart Syncthing the UI is not available for several minutes. I checked the log and found that it is scanning folders before it makes the UI available.
Could you change this so the UI is made available first? This becomes more relevant the larger and/or slower the folders/scanning get.
Greetings Fino;
No. It does not scan files; it checks the database, which is required to provide sensible answers in the API/GUI.
You can reduce startup time somewhat with the instructions in this issue:
Here a bit from my logs, i doubt that the performance problem is from hashing benchmark. Something else is happening here.
How can i debug? Maybe with “-verbose” switch? What do you suggest?
