A bit disapointed by rekordbox

Hi,

I'm using the latest version of Rekordbox on OS X El Capitan with latest iTunes version and DDJ RX. The software has stability problems, it regularly stops playing music of one deck or global sound just stops suddenly. As it was quite new when I first used it I thought bugs were acceptable but it has now been more than 6 months and it still has many problems. The major problem is on optimization, I have a recent macbook pro with ssd, i7, etc but it still takes a lot of ram and is very long to analyse musics. I was using Serato DJ before and I can clearly see the enormous difference. I'm also waiting for a day mode. I usually train during day and I can barely see anything on the screen with the dark low contrast background and day light. I also use itunes to manage my playlists but rekodbox always loose the playlist and I have to refresh it at each launch, it also loose files path from iTunes so I have to go reanalyse them and as it takes long to analyse it can be very anonying for fast mixing. I hope the software will get better soon, it has lots of potentiel and great features like support for cdj, pad effects, etc. However I won't use it for live performance for the moment, I am not confident with all the troubles I have currently. (Sorry for my bad english i am french)
