Slow gmail

I have been a regular Gmail user, and it is my contact point for almost everything. It has been fast, clean GUI, but yet recently I have noticed it to be awefully slow. Only point of attraction for Gmail was and can be -
Speed
Memory
GUI & Email Threads

Rest of features like Chat can be created else where. Google has a whole advantage in Gmail. It is time they move it from Beta to a product and ensure some Satisfaction level. I believe opening of account to everyone created whole lot of new accounts which might be loading your infrastructure. The earlier approach was better in my view. Please try something to enhance speed in Gmail or post some guidelines on it on www.gmail.com. This will indicate that problem is acknowledged and people are working on it. And hence people might not get an impression that it is not a customer friendly company. Which is very important, given there is no shortage of rivals for you guys
