     13large but <2Gb file scrolling to end is momentally. Bug (?) appears

    13 Maybe my conclusion was a bit hasty. It is indeed useful to be able  
    14 to scroll up from the end of the file.

     19It's true that the viewer takes a long time to scroll at the end of  
     20a large file.

    16 Maybe the current logic should be extended with a "from end of  
    17 file" logic. Line cache should only be filled when a goto is  
    18 executed, and while the user is scrolling through the file (either  
    19 down from the top, or up from the bottom). 
     22Did I understand you correctly that scrolling to the end of a file  
     23< 2 GB is momentarily, but it takes long only for files > 2 GB? I  
     24would have expected it the other way round, so that files < 2 GB  
     25take a long time and files > 2 GB are quick (which might indicate a  
     26bug in the code).

     28There is currently no way to avoid the waiting. It is used for line  
     29number generation, and perhaps that calculation could be delayed a  
     30bit or be done in the background. This would complicate the code,  
     31as the current commands for "one line up", "one line down", and so  
     32depend on the line numbers to be there. But it is certainly  
     33possible.

     49So sorrow :-/ But it is strange for me that time of calculation

    2664Try F5 to a line around the end of the file. This might be faster  
    2765in the old viewer. Now goto a line at the beginning of the file.
