Introduction
Symantec Café has the fastest Just In Time Compiler. In this
perfomance comparison we show you why. The second section benchmarks and compares
the current offerings from Symantec, Microsoft, Sun, and the previous version
from Symantec.
The products benchmarked were:
Symantec Café 1.5.1 with JIT 2.0
Symantec Cafe 1.5.1 with JIT 1.02e
Microsoft J++
Sun JDK
High Performance JIT (Just In Time Compiler)
The JIT, or just in time compiler, takes bytecode and turns it into native code on
the fly. The Java bytecode is usually interpreted. However, if you are using a JIT,
this bytecode is turned into native machine code and executed directly instead of
being interpreted. This results in a substantial performance boost.
Just-In-Time Compilation
One of the principle issues when dealing with Java is the performance of applets.
By using the Symantec JIT, end users will see an increase in application speed without
any additional work on the part of the applet writer.
These are some common numerical tests used on a wide variety of machines as benchmarks
of performance. Feel free to download the source and compare the performance with
your machine.
These tests were conducted on a Pentium based machine as follows:
- Dell Omniplex 590
- Pentium 90 MHz
- 32 megs of RAM
- NT 4.0 Server with Service Pack 1
