Looking for a faster Java?
Don Browning performed an
interesting "unscientific" performance test of
C#, Java, and C++ and subsequently provided the source code.
These were his original results...
Time to find the first 7 magic numbers:
1.4.0 JVM - 8.1
seconds
1.4.2 JVM - 5.2 seconds
1.0.3705 CLR - 3.9 seconds
Good Old
C++ - 2.3 seconds
I thought it would be interesting to throw both the C# and Java versions
against Alintex Script .NET
1.1 and see the results. Please note that Alintex Script .NET 1.1 has not
been publicly released and is not available from the Alintex web site.
Update: Alintex Script isnow available for
download
Isn't the result afaster Java than Java?
Time to find the first 7 magic numbers:
Alintex Script
1.1 C#code (1.0.4322 CLR) -3.7
seconds
Alintex Script 1.1Javacode (1.0.4322 CLR)
-3.85 seconds
In the screenshots below, I explicitly specify the compile (/c)
command line option so that the scripts do not receive any performance advantage
from already being in the script cache. I also specify the entry points (/et)
because both scripts use a non-standard script entry point.
I added a single line to both scripts, that displays the script
elapsed time for interest. Alintex Script provides a ScriptInfo class that can
be used within a script to obtain information such as the script start time and
elapsed time.
