Wave is faster now:)

I just had a meeting with my partner yesterday talking about our project. I logged on my google wave account to start a new wave as our meeting minutes. I realized that it is much faster now than several months ago. The concurrent control of typing is quite smooth now without delay. Google has done another nice job for us. And perhaps that's why it is one of my favorite company in the world.

But I start to think the reason behind this change. Is it because of new algorithm? Are there more severs providing the service? I guess the second point should play a role of this change. I remember that at the beginning when it was quite slow, Google suggest us to use our own servers for wave. Apparently I don't have that much money to buy/rent a server for that purpose, but now the performance has enhanced. That means the server which serves my wave has fewer workload than before. And I asked my friends on wave, they also have this feeling. And I am quite happy that we can chat in a wave, seeing everyone typing and erasing now.

If more servers are there, would it be related to cloud computing in the future? If companies are suggested to buy/rent their own server for the use of wave internally and users are suggested to buy/rent their own server for the use of wave with friends, isn't it business of cloud computing?If so and wave is really penetrating into all areas(blog, email, IM etc) , then it could be one of the successes of cloud computing in the following years:)
