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.
THX
Here my hardware.
