-one of the costly things at the moment, is RangesIO#offset_and_size, -which is called for each write, and re-finds which range we are in. -that should obviously be changed, to a fixed one that is invalidated -on seeks. buffering would hide that problem to some extent, but i -should fix it anyway. -

potentially searching -through Dirent#children at creation time. - -to test, i'll profile creating 1_000 files, without writing anything: - - user system total real -write_1mb_2x5 16.990000 1.830000 18.820000 ( 19.900568) -
