About Speedometer About Speedometer Speedometer measures simulated user interactions in web applications. The current benchmark uses TodoMVC to simulate user actions for adding, completing, and removing to-do items. Speedometer repeats the same actions using DOM APIs — a core set of web platform APIs used extensively in web applications — as well as six popular JavaScript frameworks: Ember.js, Bac

How much does your framework choice affect performance? The answer may surprise you. Authors’ Note: We’re using the word “framework” loosely to refer to platforms, micro-frameworks, and full-stack frameworks. We have our own personal favorites among these frameworks, but we’ve tried our best to give each a fair shot. Show me the winners! We know you’re curious (we were too!) so here is a chart of
Research Topic Cart & Checkout Usability Research 70% of all e-commerce visitors abandon their shopping cart. Why? At Baymard we’ve tracked the global average cart abandonment rate for 14 years, and it currently sits at 70.19%. After e-commerce sites have invested vast resources in “first in mind” strategies, Pay Per Click campaigns, beautifully crafted homepage imagery, faceted search logic, etc.
PHPフレームワークの速度比較では、HelloWorldを表示するのみの単純なアプリを用いた計測を元に比較表が作られることが多いです。特に後発のフレームワークは分かりやすい特徴付けとして速度をアピールする傾向にあるため、その比較表を元に N倍速いというアピールをしています。 PHPフレームワークを使うということは、DBまで絡めたWebアプリを作ることがほとんどなため、HelloWorldアプリの比較よりは、DBからレコード取得して表示するまでの処理速度を比較したほうがより現実に近い指標になると思います。特にCakePHP1系ではDBのデータ取得も独自ドライバになっていますし、モデルの処理も重いのでそこまで含めて他と比較したほうが良いと思ってます。 今回はDBから1レコード取得して表示するという簡単なアプリで各フレームワークの速度を評価しました。フレームワークに備わっているViewキャッシュ
A Comparison of Approaches to Large-Scale Data Analysis: MapReduce vs. DBMS Benchmarks Overview 04/14/2009 - SIGMOD 2009 Paper The following information is meant to provide documentation on how others can recreate the benchmark trials used in our SIGMOD 2009 paper. Our experiments were conducted on a 100-node cluster at the University of Wisconsin-Madison; each node had a single 2.40 GHz Intel Cor
PHPBench.com was constructed as a way to open people's eyes to the fact that not every PHP code snippet will run at the same speed. You may be surprised at the results that this page generates, but that is ok. This page was also created so that you would be able to find discovery in these statistics and then maybe re-run these tests in your own server environment to play around with this idea your
多くのプログラマにとってメモリアクセスの速度を気しなければならない状況というのはめったに無いが、OS、ライブラリ、コンパイラ、RDBMSなどの実装をする時には意識をしなければならない場合がある。 IA-32 Intel Architecture Optimization Reference Manual (order number 248966) をひもとくと6章にOptimizing Cache Usageというのがある。 マイクロベンマークの定番 lmbench http://www.bitmover.com/lmbench/ では、一次キャッシュ(L1)や二次キャッシュ(L2)を測定してくれる。例えば、わたしが利用しているノートだと、L1が1.776nsでL2が5.3490ns、メインメモリアクセスが139.4nsである。 Memory latencies in nanosecond
speed/validity selectors test for frameworks. Every framework runs in his own iFrame, thus no conflicts can happen. Tests are run selector by selector, with an interval to prevent the browser from freeezing. Tests are run in a neutral environment, no library or framework is included in the main javascript test, to avoid favoritism. Tests are run against a local copy of this document. beta' src='s
