When it comes to troubleshooting an application performance issue, where do you spend the most time?

With the tools available nowadays, I find Root cause and problem Identification can be quite quick. But Remediation takes time due to the process & procedure in place that needs to be followed.

Root cause analysis - you will probably see the problem again.

Telling the customers it's not the network!

Other: Who to blame.
The attitude has been the other 3 choices are secondary to whose fault it is, real or imagined. It has rarely been find it, fix it, then go over how it happened & how to prevent.

BTW the 'imagined fault' translates to: "I'm the one who messed up, but I spin it to blame you."

Most of my time is spent in my chair :)

Other: Preventing the isolated conditions from occurring again.
