Just by way of more info I was editing a gitolite conf file of 4096 lines with
the following stats to render the syntax with the cursor at the end of the file
The total time taken was 5 seconds. By default redrawtime is set to 2 seconds
so the 5 srconds taken represents a considetable drop off in performance. It
is true that 18.04 feels sluggish. Maybe Spectre malware fix slowdowns?
