Dear all two days ago i upgraded from 15.10 and immediatly i experienced a great loss of performance. Loading a 8 Mega database taked more than 10 minutes. Computing was very slow. Instead the speed of loading of the same database in another pc less powerful is very fast. Initially i thought the reason was an upgrade failure so today i installed few times a fresh version of 16.04, but with no effect. I was unable (i had some trouble in compiling the .tar ) to try if the 2016c version was working. I cant downgrade to 14.04 because i need an higher version of gretl and but i cant work with this trouble. So - really - any help or suggestion is very appreciated.
