Computer used in tests is a standard home desktop computer bought for $ 1000:Intel(R) Pentium(R) Dual CPU E2200 @ 2.20 GHz, 2.99 GB RAM.
Prior to generating the data, indexing and testing, there has been no preparation of the computer done nor has there been any disk defragmentation software used, i.e. the station was used in the current status "as is".
During test queries a disk space of the station was used up by 95 %(full size of disk space is 390 GB).
Platform: Microsoft Windows XP Professional, version 2002, Service Pack 2.
During the tests the computer was connected to the Internet, anti-virus system was active.
When saving the source base on a portable hard disk Seagate FreeAgent,the system works via USB-channel at approximately the same speed.Search time is the same as in case when the database is located on the hard disk.
