thx erik, that answered my question
Ryo-ohki, this is puzzling me. I entered into your shop and works great! what am I doing wrong? It’s bizarre that when I try to install it with chrome, it generates ~35 tables. And then it stalls. With Firefox, it generates ~ 90 tables before stalling. And with IE 9, it generates 126 tables and the progress bar in the top never dissapears.
It could be something with my MySQL server, the timeout setting, or something like that? how many tables has your prestashop db? Last night MySQL was behaving very badly, I even contacted technical support. Basically, I couldn’t edit nothing in any database (as if they were read-only!)… By the time they checked it, everything was working fine… so many years being a promoter of dreamhost among my friends, but recently I’m having strange issues 
OpenCart installation was nicely done (http://www.nett.mx/semsational/opencart/) but I want to have more options for doing the benchmarking.
Thanks in advance!
