Know can I know how much object has been created?


#1

Hi,

We have an application which is very time and ressource consuming, so
we would like to know how to monitoring the number of object created
and the size of memory used by ruby? is there any API that we can use
or where can I find the documentation about this???

Thanks you very much

Not much info to go on, but assuming you’ve ascertained it’s not bound
by network latencies, or web or database server latencies:

Object counts: something like:
c=Hash.new(0); ObjectSpace.each_object {|obj| c[obj.class]+=1}; pp
c.sort_by {|k,v| -v}
