 - 0 fragmentation - no byte loss while storing file name of directory entries
 - no copying of filename strings while sorting/filtering
 - entries not matching a filter are moved to the lowest slots to ignore later
+- selection handling through optimized bulk memory manipulation
 - increased number of open file descriptors
 - fast redraw only affected lines to avoid complete refresh
 - all the large buffers are aligned
 - frequently used structures optimized to facilitate SSE quad-instruction support
-- readahead request (to kernels supporting the feature)

 - fast routines to calculate and render file size
 - shifts instead of div and mul (modern compilers do this already)
 - optimized memory usage everywhere, buffer re-use
