Thanks for your feedback,
Following your suggestion, I looked how the logo appears in many browsers.
In IE, Firefox, Chrome and Safari (that are sharing about 97% of the market) the logo looks just fine. I saw that in Opera it looks a little bit edgy as the ones of many other websites with Opera.
I am willing to look into it later. It is good I know the issue at least.
I did change font size, color and style. What do you think, is it better now?
About the layout I am glad you like it. Simplicity and usability are what I am looking for.
I also did some tests about the loading speed... You are right. I will work on it tomorrow and I will let you know the results.
This is the detail of the requests for the main page of my website:

Now it takes 2.2 seconds to load with 30 requests.
In addition, I am thinking of replacing all tables in the page with divs.
Do you think it will help?
Thanks again, I will keep you update!
