Heavy memory usage on small CoG (Tiffs) files #143
Description
Describe the bug
I am noticing great memory usage when loading even small COG files in the band of 3~6MB.
I see a bump up to 300MB in memory usage after loading on map just one COG.
In my scenario I have to interchange between a lot small TIFF files loaded.
This results to great memory overhead, which might lead to possible crash.
My files are required to have a good resolution at zoom level of 21 in order to see some details. As such I am using resolution: 256.
Can I do something to reduce the memory overhead with preprocessing of data? ( gdal, or other COG related tools ).
Also the zoom in/out in high zoom values ( 19~21) is not smooth.
Is this something within tool limits?
Is there space of optimization within the code to try to spent some time on?
I am using nuxtJS ( vueJS 3) without the vuejs-leaflet module.
To Reproduce
Steps to reproduce the behavior:
- Load a COG file to the map
- Navigate to the browsers developer tools and take a memory snapshot.
Expected behavior
A multiplier for 3MB tiff file could be in the range of 10X but not 100X in memory consumption.
