HTC Phones - Android 2.2 Froyo Compared To 2.1, Froyo Is 450% Faster

Android Police has made a test on a Nexus One that is running Android 2.2 Froyo, compared to Android 2.1. And here is the result: Android Froyo is 450% faster than 2.1. Android Police use LINPACK to test the performance.

A brief introduction to Linpack:

The LINPACK Benchmarks are a measure of a system’s floating point computing power. Introduced by Jack Dongarra, they measure how fast a computer solves a dense N by N system of linear equations Ax = b, which is a common task in engineering. The solution is obtained by Gaussian elimination with partial pivoting, with 2/3*N³ + 2*N² floating point operations. The result is reported in Millions of FLoating-point Operations Per Second (MFLOP/s, sometimes simply called FLOPS).

This test is more a reflection of the state of the Android Dalvik Virtual Machine than of the floating point performance of the underlying processor. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time.

What is the purpose of this app?
This is a simple benchmark test to show performance relative to other phones for a standard calculation.  Linpack has been used for years on all types of computers, with a version used to rate the TOP500 computers in the world.

What speed is better?
A higher number is better.

Does having faster speed improve the android phones or what?
Yes, it should.  The Dalvik VM has a huge impact on the Linpack number.  A better number on the same device would indicate that a new version update has improved performance.  Or it could show that something has gone terribly wrong if the number goes down.
