Topic: Performance Issue... Where is the time gone?
I've been working for a few weeks on a Rails project (I am sort of a beginner... so it was longer that it should have!).
I am now testing my app in its production environment whil keeping it closed to other users, and I am facing terrible performance problems!
I've used Rawk to identify the bottlenecks in my app, and I was able to identify that many request take "infinite" time to be treated, like this one :
Completed in 14.74947 (0 reqs/sec) | Rendering: 0.92342 (6%) | DB: 1.57776 (10%) | 200 OK
The DB is bad... I know, and the rendering isn't good either, but how come I get a Completed time in 14.8 sec, with 1.6 in DB and 0.9 in renderding? Where are the 12 remaining seconds?
