Maybe just check/confirm that the issue is multithreading on the 
decoding side (which it looks to be) with:

gdal_translate web_mercator.tif web_mercator_jpeg.tif -co COMPRESS=JPEG 
-co BIGTIFF=YES -of GTIFF -co TILED=YES -co BLOCKXSIZE=512 -co 
BLOCKYSIZE=512 -oo NUM_THREADS=ALL_CPUS

where web_mercator.tif is LZW or Deflate compressed
