npm_lazy A lazy local cache for npm Why? npm can be slow, down or return random errors if you have large deploys npm_lazy caches packages on your local network, making things faster and more predictable If 100 servers request the same package metadata at the same time, npm_lazy makes sure that (at most) only one request goes out to the npm registry. No database to install, replicate or manage. Dat
PHP Image Compression & Caching A simple PHP class that compresses images on-the-fly to reduce load time and web-page resource management. Image Cache is a tiny PHP class that accepts a .png, .jpg, or .gif image then compresses, moves, and caches the image in the user's browser.

October 8, 2012Better Performance – Speeding Up Your CakePHP Website It seems that whenever I mention CakePHP to the developer community, those who have not used it think of it as a slow framework.

過負荷に耐えるWEBサービス作成のための使えるPHPキャッシュテクニックまとめ。 サービス展開というとOSのチューニングや各種インフラソフトウェアのチューニング、更にはWEBアプリプログラム自体の効率化と、幅広い知識が必要になってきますが、PHPでWEBアプリを作る際によく効くキャッシュテクニックを用途・使いどころ別に説明します。 キャッシュをうまく効かせることで大幅に計算量を減らしてより多くのリクエストを少ないマシンで捌くことが出来、コストを下げたり、過負荷の悩みを減らせます。 個人レベルでのWEBサービス開発の場合、サーバ代がお財布を大きく圧迫しますが、最低のコストでサービスを賄うことに繋げられます、ということでPHPでサービス作ってやろうと思っている人は参考にしてみて下さい。 static変数でキャッシュ 特に何も入れなくてもそのまま使えるstatic変数。例えば、関数等で一定の計算
