[性能]一个关于各种流行语言的测试

mikespook

如果因为本贴引起某些人的口水肆意，那我将非常遗憾～～呵呵～～

http://shootout.alioth.debian.org/sandbox/

在这里可以做各种语言的性能测试，如B树，正则一类的，还有一些测试我也不知道具体是什么来的～～可以看下面的英文解释～～～

总体上说PHP的性能并不是特别理想～～～python和perl甚至在多数测试上还要更好一些～～如果能弄清楚每项测试都是什么，或许有助于理解PHP的一些内在机制～～

binary-trees
Allocate and deallocate many many binary trees

chameneos
Symmetrical thread rendez-vous requests

cheap-concurrency
Send messages between linked threads

fannkuch
Indexed-access to tiny integer-sequence

fasta
Generate and write random DNA sequences

k-nucleotide
Hashtable update and k-nucleotide strings

mandelbrot
Generate Mandelbrot set portable bitmap file

n-body
Double-precision N-body simulation

nsieve
Indexed-access to boolean-sequence

nsieve-bits
Indexed-access to bit-values

partial-sums
Naive iterative summation: power sin cos

pidigits
Streaming arbitrary-precision arithmetic

recursive
Naive recursive-algorithms: ack fib tak

regex-dna
Match DNA 8-mers and substitute nucleotides for IUB codes

reverse-complement
Read DNA sequences - write their reverse-complement

spectral-norm
Eigenvalue using the power method

startup
Measure 'hello world' program startup time

sum-file
Read lines, parse and sum integers

数据的真实性无法估计，因为
"(alpha)" benchmarks are just experiments - we'll probably change them or decide not to use them at all.

Please don't waste your valuable time implementing alpha benchmarks shown on The Sandbox.

适合的，才是最好的。

php的语法适合懒人用，这个无人能敌

PHP 语言的松散性反而使人必须更加小心面对可能的和潜在的错误。

入门容易，高级难。
