Completed in 1.48324 (0 reqs/sec) | Rendering: 0.08862 (5%) | DB:
In most production logs I have seen rendering plus db comes close to
adding up to 100%; maybe 60% to 80%.
In this new app, I am getting the results above. The 0% DB I assume
comes from a cached query.
What I don’t get is what is happening with the rest of the time?
In general, where is this time accounted for?
Any guess on what might be happening?
I went through the recent railscasts and ran rawk plus
script/performance request (result attached). The biggest offenders in
my app are IO#read (20%) and MySQL#get_length (10%). This makes some
sense because I am requesting a lot of records from the db but if so,
why is DB time listed as 0%.
Any thoughts or pointers would be appreciated.
