What an update!
I downloaded v0.14.2rc2 version to a new Linux Ubuntu 16.04 and tried to synch from scratch - but I mean from scratch = 2011. It took me only 2 hours to download AND index the blockchain (txindex=1 in the litecoin.conf file)... amazing!!! It used to take me at least a day on the same PC.
Nothing special with my HW config - a 2013 hardware, AMD 4300 chip with quad core, 8 GB of RAM, HD 7200 RPM - however, I did put "dbcache=3000" in the litecoin.conf file ... allowing my unused RAM to validate those blocks more efficiently !
Great work LTC devs!
