Loading a 4 GB file with qemacs takes less than 1 second. However jumping to the end of the file takes 1 minute. I thought at the begging that there would be some lazy loading behind the scenes, but not. The data is in memory, however going through the buffer is very very slow. I made some local optimizations, but there would be much much to much work to  make such operations faster than with vim.

Viq was intentended to be a project to add vim like interface to qemacs…
