Sorry for wasting your time with my problems, but since I
changed the i386 computer, I can not reproduce the speed difference
anymore. And I do not have access anymore to this computer where the
query was running faster to double-check wether everything is exactly
the same than on the new one.
As I had better to spend my time on analysing some data with
my script rather than analysing the script itself, I eventually
swiched to DBI::SQLite, which solved my problem by performing the
query in a few seconds.
The query was something like :
$query = "SELECT * FROM $db_table WHERE SYMBOL1 LIKE \'%${Search}%\' OR
SYMBOL2 LIKE \'%${Search}%\'" ;
my $sth = $dbh->prepare($query);
$sth->execute;
(actually CLIKE, before the transition)
You may wonder the purpose of this mail, as there is no new
crucial information. The reason is that I do not like not knowing the
end of the story when I browse archived threads.
Anyway, many thanks to all that tried to help me.
