On Friday, after weeks of benchmarking T5120 and T5220 and studying the Sparc T2 (Niagara 2 chip) architecture, I finally put one in production and the results have been very promising. Though Friday evening wasn't a peak period, we experienced 62% more throughput than the previously deployed V210. I expect T5120 to be able to handle our peaks without breaking a sweat.
We'll have to take a hit in certain database operations to benefit from this 62% gain. (Update: however, luckily, those operations do not occur everyday.) I will be presenting results of my benchmarks and information at the MySQL conference. If you are evaluating Sun servers for MySQL, you will find my session very interesting.
Now, I can't wait to receive bunch of T5120s to replace all our db servers.
