is that anyway to reduce the initContent loadtime?

Well the first thing I notice is that your database total query time for this page took 1.4 seconds.  That is way too high and either means you have a poorly configured database server, poorly configured database tables (indexes for example), or poorly written query statements, or a mix of all of it.

There are a couple things I would do first

1. Install a fresh copy of PS v1.6.1.6 on the same server in a subfolder.  Leave it out of the box settings and run the profile again to see how it works out of the box
2. Then install a fresh copy of PS v1.6.1.17 on the same server in a subfolder.  Leave it out of the box settings and run the profile again to see how it works out of the box

That will tell you if the issue is with the version of Prestashop being used.  If the profile timings are about the same for both of those versions, then the issue is your server.

 

However if both installs out of the box are better than you have now, then you likely have installed a module or theme or some customization to cause this issue.
