Sunday November 11, 2018 the Mushroom Observer database server was upgraded from 4 CPU cores to 6 CPU cores and the available RAM was doubled.

Around November 22, Alan Rockefeller analysed the logs to see what the impact was. He compared the previous week to the entire month of October 2018 and found:

Average time to respond to requests pre-upgrade: 2.29117 seconds (every request in October averaged)

Average time to respond to requests post-upgrade: 1.57632 seconds (every request in the past week averaged)

技術的負債の分類 (Kruchten et al., 2012)

• コードの負債は見えるので検出し易いけど、アーキテクチャの負債は見えないので大変
• アーキテクチャの再構築、リファクタリング

可能的代替システムとの差異(Schmid, 2013)

• 負債の要因や意図を問わないモデル化
