Hello to all,
Some suggestions for slowing down jdownload, after observation.
A slowdown of this nature is probably caused by a search for the application of one or more elements that is not found.
I was able to see in particular by displaying the categories that the application was looking for a creative user, who no longer existed.
Also another suggestion would be to dissociate in the administration the validation, the download and see the modification of the name.
Indeed some shared hosting does not always offer extraordinary performance and does not allow a succession of instructions, it would be easier to modify some aberrations that may occur ...
I am well aware that this is a lot of work...
