Hi Jaap, thank you for all your help on this.I just tested the development branch which seems to include your mentioned fix. Sadly zim startup took approximately the same time as before. Maybe my use case is abnormal? If so I don't want you to spend lots of time on this.
Below the output of ./zim.py -V -D. All the time is spent in BackgroundCheck. Is this what you would expect? May we (I?) add debug messages to track the time spent indexing large files?

Hi Mario,Just pushed a fix (29bdea) that improves how we check whether files are a zim page or not. Now max 50 characters are being read at the start of the file when indexing. If your large files are not "line based" (thus resulting in a very long read when trying to read the first line) this should fix the issue.Regards, JaapOn Sat, Apr 24, 2021 at 10:06 AM Mario Bezzi <subscriptions.mario.bezzi@xxxxxxxxx <mailto:subscriptions.mario.bezzi@xxxxxxxxx>> wrote:Hi Jaap, thank you for your help on this. To give you some more details: Of the 3000+ files which size sums up to 2GB, the top 500 account for 1.6GB. Among these the average size is 3.5MB, and each of the top three is in the 250MB range.

You are referring to this issue: Make indexer ignore text files that are not zim pages · Issue #907 · zim-desktop-wiki/zim-desktop-wiki (github.com) <https://github.com/zim-desktop-wiki/zim-desktop-wiki/issues/907> which is fixed in the development branch and will be in the next release. With that fix the indexer will read the first line of each file to decide whether it is a zim file or not, and if not it will not try to access the contents. Would be great if you have a chance to test the development branch and see whether it works in practice for your case ! -- Jaap On Thu, Apr 22, 2021 at 7:32 PM Mario Bezzi <subscriptions.mario.bezzi@xxxxxxxxx <mailto:subscriptions.mario.bezzi@xxxxxxxxx>> wrote: The folder contains 3118 ".txt" files, for a total of 2GB of data. Some large txt files are attachments. A long time ago I submitted a request to avoid indexing these. Not sure it has been fulfilled though.

To give you an idea, I just restarted Zim, and indexing kept a processor 100% busy for 13 minutes to come to an end. It was nice if this could be avoided.

Still, when it starts, Zim goes crazy for a long time indexing, and I came to the conclusion that this is normal. If this is the case, I would like to file a requirement to add the ability to make indexing optional.
