I admit this is my first experience with BaseX and XQuery language, but this seems weird and i can't find anything on docs or issues related to this.

I created a random dataset of calls and i wanted to query this dataset using XQuery,

however it turns out compile time takes too long for a relatively simple query.

The dataset can be found here .

The query is:

doc("basex/etc/dataset25k.xml")/users/user[number= "605 6230540" and calls/call/location/@city = "Sandy Springs"]/fullName

Timing:
- Parsing: 0.61 ms
- Compiling: 382.43 ms
- Evaluating: 2.1 ms
- Printing: 0.14 ms
- Total Time: 385.28 ms

Compiling:
- rewrite fn:doc(uri) to document-node() item: doc("basex/etc/dataset25k.xml") -> document { "file:///home/arcogabbo/Scrivania/basex/etc/dataset25k.xml" }
- rewrite to predicate: ((number = "605 6230540") and (calls/call/location/@city = "Sandy Springs"))
- apply attribute index for "Sandy Springs"

Even if i try a simple query on the example dataset of the application(factbook.xml) the compilation time takes too long, for example:

Query: 

doc("basex/etc/factbook.xml")/mondial/country[@name="Norway"]/province/city

Timing:
- Parsing: 0.34 ms
- Compiling: 82.29 ms
- Evaluating: 1.05 ms
- Printing: 1.49 ms
- Total Time: 85.17 ms

Compiling:
- rewrite fn:doc(uri) to document-node() item: doc("basex/etc/factbook.xml") -> document { "file:///home/arcogabbo/Scrivania/basex/etc/factbook.xml" }
- apply attribute index for "Norway"

I also tried BaseX version 9.5 and on another computer, yet compilation times are approximately the same. Any help is appreciated.
