I have very slow performance with Ubuntu 14.04 LTS and MySQL 5.5.43
I need to import 4GB in database.
12h later, the size of database is 180 mo
I did the same import with a older Ubuntu and MySQL 5.5.43
This took 3h ...

I use default settings for Ubuntu and MySQL.

Did you have encountered the same problem or Did you have a workaround ?
