[Koha-devel] Playing with NYTProf

[Jonathan Druart]

Hi Julian,
On the second profile of the real real life (nytprofhtml.21326_2), you
can see the 30% on the flame graph.
Search for 'Update' on the page, there is something I done understand.
The queries don't look to be cached (what I was expecting).
