[MonetDB-users] More timing information in MonetDB/XQuery
Hi,
I am running some XQuery queries on MonetDB/XQuery (june release) and I cannot get all timing information like trans, fetch, shred, print time. All I can get is one time ofomration Timer, which I guess is overall information about how much time did the query take. I tried to run queries both in session and from shell: 1. xquery>\t xquery><test.xq 2. mclient -lx -t test.xq
My OS is MAC OS 10.5 (Leopard).
When I tried it on Windows, I will get all the timing information.
Thank you for your time and help.

Hi Peter,
unfortunately, the detailed timing information you used to get with previous (i.e., before Jun2008) releases of MonetDB/XQuery "got lost" with the introduction of the new Algebra-based Pathfinder compiler in the Jun2008 release of MonetDB/XQuery. Since then, with the new (default) Algebra-based Pathfinder compiler, you only get the client-side wall-clock timing as measured by mclient.
The detailed timings are still available for the old (and deprecated) "milprint_summer" version of the Pathfinder compiler, which you can activate by calling `mclient -lxquery --no-algebra` (cf., `mclient --help`; see also http://monetdb.cwi.nl/Development/Releases/Version4.24/index.html#XQuery). Note, though, that the timing you get then are obviously only for the old (and deprecated) "milprint_summer" version of the Pathfinder compiler, not for the new default Algebra-based Pathfinder compiler.
We plan to re-introduce the detailed timing information for the new default Algebra-based Pathfinder compiler in some future version of MonetDB/XQuery, but the upcoming "Nov2008" release will not yet come with this feature.
Sorry for the inconvenience.
Regards, Stefan
