Server infrastructure for MBSJ2012

For the MBSJ2012, we used the following server hardware;

Vendor: SAKURA Internet
Type: 8G VPS
Memory: 8GB
Disk space: 800GB
CPU: Virtual 6 core

During peak times, CPU usage reached 80%. Even at non-peak, usage hovered around 60%. This indicates that performance was not good enough.

In the future, the complexity of Ponzu and the number of participants actively using the system is sure to increase. Hence further performance optimizations and / or more powerful server hardware will be necessary.

We will do more detailed performance analyses at a later date.

Due to security reasons, we will not disclose server software configurations.
