 # Tail Blazer is fast
 
-For Tail Blazer to be taken seriously, widely used and relied upon it has to be fast. This is why for several days my priority has been to find a way to significantly speed up the time it takes to load lines from a file. Slow performance was apparent with large files when either the file was being written to rapidly or a user was scrolling. This is no trivial problem.  In fact it is this performance difficulty which prevented me from creating Tail Blazer years ago which is wht I only started on this project when I had mentally solved these problems.

 I have managed to achieve what I believe to be impressive performance by indexing the files and virtualising the viewable area of the screen.
