This article presents results of speed tests made on the table of 10,000 records
for all known commercial database engines for Delphi,
which store all the data in the single database file.
All measurements are presented in the Table1.
Relative speeds of database engines in comparison with the fastest product (its speed is taken as 100%)
are shown on the Diagram 1.
This diagram visually presents what product is faster and how much than others.
You can see that EasyTable is the best database solution for the midle volume data.

All tests were run on the same machine (CPU Intel Pentium 4 2.4 Ghz, MB ASUS P4S8X, 512 Mb DDR400 RAM, HDD Western Digital 80 GB IDE, OS Microsoft Windows XP SP1) .
You can see that EasyTable has the fastest disk engine for middle-size databases.
It is 2.8...7.4 times faster than any product of other developers, especially for Locate operations and
all operations with indexes. EasyTable has indexing system which was specially developed
for fast work with databases of small and medium size. This and other solutions in EasyTable
database engine made EasyTable to be the fastest database for midle volume data.
In the tests with 10,000 records in the table, the Accuracer even 1.8 times slower than the EasyTable,
but on 100,000 records Accuracer shows
fantastic speed
and becomes undisputed leader.
