I am experiencing extremely high cpu and mem usage by canvas on medium size custom views when using tm1-ui-dbr as well as constant network pegging and bad input performance.
I have a simple table of 365 rows and 4 columns (+ 1 column for row labels) with each cell containing a tm1-ui-dbr. The dbrs are pulling from an attributes cube containing strings. This canvas page is using the > 2.6 Gb of ram and pegging my cpu at 25% ( maxing out the thread ) just when sitting there. The page seems to be triggering constant digest cycles with the tm1-ui-dbr when the page is loading and when it is idling. Furthermore inputting any kind of values into the input boxes is sluggish due to the performance hog when you have this many rows, because of the bad performance some inputs will not commit there values if you edit one input and quickly edit another, the first input will revert its value. Sometimes I am getting invalid cube name errors as well.
I am not getting these issues with the readonly dbr.
