Perspective - FileUpload - Bunch of files

I’m on 8.1.5

I try to upload a bunch of xml files into a database, I have 36 files and some files are not fired due to delay of insert query.

I’ve tried with asynchronous invoke and get same result.

	filename = event.file.name
	filedata = event.file.getString()
	
	system.perspective.print(filename)
	system.db.runPrepUpdate("INSERT INTO tbl_xml (filename, filedata) VALUES (?, ?)", [filename, filedata])

some files are huge +/- 2mo

I think I have the same sort of issue.
There must be some upload limits anywhere (delay to process file, size of the file, or number of files) ???
