Whoops, thanks rouault for catching that. I mixed up the wide and tall labels. Corrected now. Haven't tested other versions. Did try changing cache size to 256 MB then 2048 MB. Could try larger value too (I have 192 GB RAM). Also tried converting single TIF --> PNG, and never got past 0 pct (only ran for 10 minutes).

  • Ticket #5828 – Description

    v1 v3  
    44Given two vrt "rasters" with sizes as follows:
    55
    6 59392,201728 (wide raster)
    7 191488,46080 (tall raster)
     6191488,46080 (wide raster)
     759392,201728 (tall raster)
    88
    99performance degrades to about 20bytes/sec on the wide raster when I hit about 30% processing (still at 30% + 1 dot 3 hours later). On the other hand, performance does not noticeably degrade when processing the tall raster, and the entire translation takes about 2-3 minutes.
