Message-ID: <20130621193600.GA12712@amd.pavel.ucw.cz> Date: Fri, 21 Jun 2013 21:36:00 +0200 From: Pavel Machek <pavel@....cz> To: jaegeuk.kim@...sung.com, linux-f2fs-devel@...ts.sourceforge.net, kernel list <linux-kernel@...r.kernel.org> Subject: f2fs tests Hi! I played a bit with f2fs... First, I had to compile the f2fstools... Unfortunately they require never autoconf than available on debian. I tried to hack it, but then I decided that compiling it by hand is just simpler. gcc -I include/ -I . lib/*.c mkfs/*.c /usr/lib/libuuid.so does the trick. I was quite surprised there's no fsck in the repository... Do you have fsck somewhere? I tested with copy of kernel and 4GB stick (with RedHat logo, thanks :-)... copying it from hdd took 46 minutes for VFAT and 19 minutes for F2FS. Good. VFAT: time find . -name "not-here" took 26 seconds. F2F: time find . -name "not-here" took 22-24 seconds. Faster copy, same speed find, good. (Find is even slightly faster than HDD, with 27-30 seconds). But now the strange stuff: the same data takes 861MB on ext3 and 1.3GB on f2fs. (It was even bigger than that on VFAT). I guess I should test the patch for inlining small files into inodes?
