Michael Shigorin c2996cc493 stage2: 99-elf-stats for squashfs tuning ... This kind of test was proposed by led@ to gather statistics on chroot's contents going to become squashfs (the script optimizations lowering added overhead from ~10 sec down to a subsecond range were also proposed by him). Intentionally not documented in doc/variables.txt due to the rather lowlevel nature of the probe (at least so far). The knobs involved are SQUASHFS (the additional effort kicks in only for "tight" case) and GLOBAL_SQUASHFS_SORT (must be non-empty for this extra overhead to occur). Additional experimentation is needed to find out whether the difference in squashfs size and performance is worth the trouble (seems the impact is non-zero but pretty minor).		2012-04-09 22:03:29 +03:00
