Hello,
Great that the logo issue is resolved!
Regarding performance:
Inspecting your website I saw your images are very very big in terms of bytes size. Probably this is affecting a lot your performance. You should resize these images to fit the container size where the images are. For example, if you have a container with 300×300 pixels, then consider to resize the image to 300×300.
Here’s the images:

Here’s another things you can do about performance:
Regarding performance, there are a few things you can do after you finish your website. For example, there are several different ways to compress and combine the assets, this is probably the easiest way: http://www.okler.net/forums/topic/minify-php-how-to-combine-minify-and-cache-javascript-and-css-files-on-demand/
The images can also be improved, consider to export them in a lower quality. JPG 80% is good enough.
Regarding the cache, this is the right way to do that: https://developers.google.com/speed/docs/insights/LeverageBrowserCaching
You can also remove the plugins that you will never use in any page and combine/compress all the other scripts so it will cache the resources and make it much better in performance in any other page.
The use of a CDN to serve your website files also it’s a good idea.
It works the same way for all HTML templates. All files come uncompressed to make it easy to edit and customize, and then when you finish your website you can make the improvements.
We hope this helps!
