以前、全て解約したさくらVPS
だけど、今回、DB負荷の高い処理用にSSDプランを契約してみた。
DBはオンメモリ出来ない処理が発生した場合、ディスク性能が大きく物を言うわけで、SSD搭載機種はレスポンスが良くなる感じ。
8GBメモリ＋SSDプランで、とりあえずいつも通りUnixBenchしてみる。

先日のお名前に比べるとやっぱりCPU性能は低いけど、ディスクI/O、特にマルチスレッド時の低下が少なく、ぐりぐりとtemp on fileやり出した場合に性能が良い感じ。
あとは、さくらはローカルネット構築機能がついたから、複数台を使ったシステムを動かすのにも良さそうだね。
お名前もローカルネット構築機能つけてくれないかなぁ・・・
