This is the second case with the same scenario:
-the customer uses MySql on Linux for more than 5 years without any problem
-they buy a brand new Pc (about 3 times as fast as the Linux computer), intall Windows Server on it and MySql
-migrate all the data
-the software which uses the MySql database will be about 10 times slower
How can it be that on a much faster computer the MySql is so much slower?
Is it about the differences between the operation systems or the MySql on Windows needs some special parameters?
(by the way the mysql.ini had the same settings on both).
Thank you very much.
