One area that has been reported to have a big impact is the number of locales. The other person I worked with ended up with inconclusive results. I was going to try the same experiments with you to try and see if we could identify the cause of the radically different results. Very hard to diagnose, but almost felt like maybe different anti-virus software or other background jobs could be kicking in (or machine thrashing etc). Never worked out why, but different people running exactly the same code were having different performance.
I was working with someone else - their machine was going a lot slower than expected. So we have to work out what is different in your circumstance.
(I am not saying it is not slower, only there is not much information to work on.) Not everyone is having the same slow down as you, so 1 minute page loads is not a generic problem.
But it is not clear from your report how slow it is still going, and what you are doing that makes it slower than for other people. Hi - which of the approaches other people have suggested have you tried? And did you send me an email as I requested? Sorry if I missed it.
