Upgrade From 2.x.x To 4.x.x

Tried all the optimization tips but my 4.1.3 is still as slow as poison

with zero products. Can't have anything to do with NOT loading sample

products during installation.

It 'may' have to do with it being in a sub folder but probably not because

so is a lot of 3.0.6

Not a biggy until my web host closes down the PHP 5.3 legacy server.

Then I will have to jump into 4.1.3 but most likely by then the SAAS

will be up and running.

All I need right now is Image Zoom in my 3.0.6 and I will be short term happy.
