Does exists solution for displaying debug information such as db query count, db query listing, page generation time, peak memory usage and etc. Something like symfony debug toolbar https://3.bp.blogspot.com/-qP9aQBIcsqo/T4iPhy6KCBI/AAAAAAAAB0w/CsFjx4UGKG0/s1600/Screen+Shot+2012-04-13+at+4.39.20+PM.png P.S. Is there a way to monitor what is going on with the script?
