I have upgrade to the latest rails and activescaffolding, I am processing the data to .xml format. when i hit the url like server/tablename.xml , it is utilizing 100% CPU and after the request it is normal. Does this is acceptable ? is this an issue.
100% CPU utilization means: hey I am working on processing your data.
So thats total normal and acceptable.
The only issue could be: how LONG stays the CPU at 100% ?
And the answer is: it depends, how many data has to be processed, how complex is the computation, etc
But why are you asking? Is there a difference before and after your upgrade ?
