前エントリーから一部の内容を分離して追加記事にしてみました。以下実施したメモリ増設の効果について。 ここ数ヶ月、自宅サーバの負荷がだんだんと上昇してきていて、そろそろ1台で高速にさばききる限界に近づいてきた感があったり。ここ数週間のロードアベレージはこんな感じ。グラフは× 100 の値になってます。CPU のコアが2個なんで、200 まではOKということでまだ処理しきれているわけではあります。ちなみに mrtg グラフは瞬間値を示しているわけではなく平均値なので瞬間的にはもっと負荷が高いときとかあります。 でも月次処理が走るともっさり感満点。 ※緑‥1分平均 / 青‥15分平均 実は CPU の処理速度が追いついていないと言うより I/O 周りがボトルネックになっています。 ※緑‥読取ブロック数 / 青‥書込ブロック数 ということで、メモリを2GBプラスして、合計 4GB にして参照系
