My first test are complete. ;)

Summary:

MySQL, ProLiant DL180G5, CentOS 5.2

1. Batch inserts 10M unique! records in table 'File' (DB schema not
changed) : 39 hours (23+16), DB file size 15,4 Gb
2. Batch inserts 10M unique! records in table 'File' (NEW DB schema
see also create_mysql_test2.sh) : 35 hours (19+16), DB file size 15,2
Gb

Source code attached.

Please note that the length of time (16 hours) insert records from the
table 'batch' to the table 'File' the same.
This indicates the stability of results.
