Crazy @Tesla video from a week ago. Just saw it on Reddit.

Driver was trying to park the car and then things went awry.

Parking button didn’t work.

Breaks didn’t work.

It just kept on accelerating.

Query caching performance increased by 40% in #pgpool

[Tatsuo Ishii @tatsuo_ishii]

Pgpool-IIのin memory検索結果キャッシュで排他ロックを使っていたのを共有ロックにしたら、最大40％くらい性能が上がった。赤が今まで、緑が改善後。青はキャッシュを使わない時（参考用）。縦軸が秒あたりの問い合わせ数、横軸が同時セッション数。
