The performance of InterBase Server 5.0, Sybase SQL Anywhere, Microsoft
SQL
Server 7.0, InstandDB, Cloudscape and Hypersonic SQL was compared.
It was
assumed the databases that are not written in Java would be much faster
because they
are written in C, C++ or Assembler, and because Hypersonic SQL is until
now not
optimized for speed.But the contrary was true:
The current version of Hypersonic SQL is (using this simple tests) always
faster than
all the other databases. Sometimes more than 10 times! The reasons
for this are not
fully clear. One reason may be that Hypersonic SQL does not organize
the data in a
traditional file oriented way.
Results
The results indicate the time (in seconds) required for executing the
commands. Smaller
is better. There are currently no results for Microsoft Access, but
the results are similar
to InterBase and Sybase. The results for Cloudscape are not included
in the graphic
because this would disturb the picture.

Remarks
All databases are run with enough memory (no swapping) on the same computer.
The databases are:
Test Program
The tests have been executed on a computer with Windows NT 4.0, an AMD
350 MHz
processor, with 128 MB RAM. The test program is included in the DatabaseManager:
Commands/Test Script. The JDK 1.3 has been used. When running the database
inside
a browser, Hypersonic SQL it is much slower, because the Java Virtual
Machines in
browsers are currently quite slow.
The following statements are tested:
CREATE TABLE Test(
Id INTEGER PRIMARY KEY,
FirstName VARCHAR(20),
Name VARCHAR(50),
ZIP INTEGER)
INSERT INTO Test VALUES(#,'Julia','Peterson-Clancy',#)
UPDATE Test SET Name='Hans' WHERE Id=#
SELECT * FROM Test WHERE Id=#
DELETE FROM Test WHERE Id=#
DROP TABLE Test
where # is a loop from 0 to 1000
