Stock page too slow [Symfony debugging]

[Kami Solutions]

Hi,

 

I've been looking at how to use symfony without any success since I'm having issues in the backoffice, especially with stocks page that loads way too slow, it takes up to whole 65seconds to load!  Just one page! The other pages takes also a lot of time, but when I check symfony debugger there are no errors, just a bunch of missing translations, might this be the cause of the lack of speed?

I have two exactly shops (because I cloned them) with same version 1.7.6.1 at the same server, and one is loading good and the other one is extremely slow, how can I debug this issue?

 

Thanks in advance
