I've written multi-threaded regex-redux benchmark for D language
and made some tests. This is my first program written in D, I
didn't know much about D a week ago.
Here are the results for other languages:
http://benchmarksgame.alioth.debian.org/u64q/regexredux.html
I have newer CPU than one used on this page. Tests were made on
Debian 8 with i7-3770 3.4 Ghz (4C/8T) CPU.
I've tested C and Rust besides D becasue those are the top two
languages on this benchmark.
Rust version 1.16 (newest stable)
GCC ver 4.9.2 (newest debian 8 stable)
I've changed target-cpu in Rust compile command to match my cpu.
C was the fastest (1.32) but used the most CPU, D was second
(1.45) with lowest CPU usage!, Rust was third (1.55). In this
benchmark D is faster than any other language besides C.
Code in D is very clean and readable, GC is operating normally.
Exacts results are below:
D
User time (seconds): 1.91
System time (seconds): 0.14
Percent of CPU this job got: 140%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:01.45
Average shared text size (kbytes): 0
Average unshared data size (kbytes): 0
Average stack size (kbytes): 0
Average total size (kbytes): 0
Maximum resident set size (kbytes): 263848
Rust
User time (seconds): 2.72
System time (seconds): 0.09
Percent of CPU this job got: 181%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:01.55
Average shared text size (kbytes): 0
Average unshared data size (kbytes): 0
Average stack size (kbytes): 0
Average total size (kbytes): 0
Maximum resident set size (kbytes): 199008
C
User time (seconds): 4.51
System time (seconds): 0.08
Percent of CPU this job got: 346%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:01.32
Average shared text size (kbytes): 0
Average unshared data size (kbytes): 0
Average stack size (kbytes): 0
Average total size (kbytes): 0
Maximum resident set size (kbytes): 151716
I got inspired by those results that's why I thought I will write
all the other benchmarks from benchmarks game also for D and
share the code and results on github + comparison to couple other
languages.
