Compression requires zlib to be available, otherwise resources will be included uncompressed - in either case via BIN2C. It can also be disabled via ./configure --disable-resource-compression Size figures: graph.css 7752 graph.css.min 6655 (css is always minified) graph.html 2153 No Compression graph.css.c 40026 graph.css.o 9344 (6688) graph.html.c 13016 graph.html.o 4848 (2186) With Compression graph.css.c 10206 graph.css.o 4368 (1718) graph.html.c 5725 graph.html.o 3632 (971) Numbers in brackets: .rodata size from 'size -Ax -d *.o' Signed-off-by: softworkz <softworkz@hotmail.com>
