Rép: Re: Rép: Re: Slow XQueries on a quite small database but great number of docs
Hi I don't know why but the problem is present even with the basex simple client (not client/server ). It seems java (tried many versions) doesn't execute normally : display or computation is halting, jolting.... The result of the query is quite fast but the display of the result very very halting. I'm on a readynas server running on an ARM processor. I think the io library of java (buffered io or something like that) has a problem. I'm very disappointed because that database seems very well adapted for my project... Jm Christian Grün <christian.gruen@gmail.com> a écrit :
I can't run the GUI, I don't know why, I'm over a VPN and when I try the administrator login on the 1984 port, the GUI answers : access denied...
I have tried basexclient -o output.xml : Same result, the query you know takes 11s...
So I’m pretty sure it must be your connection, and not the query processor of BaseX, that slows down the query.
What about running the GUI locally? It’s not based on the client/server architecture [1].

Hi Jean Marc (cc to the list),
What happens if you run the query in the GUI (how long does it take)? How much time is spent if you write the client output to a file (basexclient -o output.xml)? Which client do you use?

Many many thanks for your quickness ! Yes I optimized the database (OPTIMIZE ALL). I don't undestand where the pb is. The query I ran is the one I have transmitted to you in the last mail. So there is a pb with the server I'm afraid. May be with java ?
When I try to execute the query from basexclient, I'have a immediate answer but a very very very slow display : lines are displayed in blocks of one or two screen terminals... There is a problem with the data exchange between the daemon and the client I think...
If you need more help, it would be great if you could provide us with a self-contained examole. Am 02.02.2016 10:40 nachm. schrieb "ansel.jm" <ansel.jm@free.fr>:
