Message-ID: <4CFE7347.8030807@redhat.com> Date: Tue, 07 Dec 2010 11:47:51 -0600 From: Eric Sandeen <sandeen@...hat.com> To: ext4 development <linux-ext4@...r.kernel.org> CC: Jan Kara <jack@...e.cz> Subject: [PATCH 0/2] ext2, ext3: speed up file create workloads The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks, thanks to page size limits. The directory entry checking can also be optimized a bit by sprinkling in some unlikely() conditions to move the error handling out of line. These 2 patches speed up a bonnie++ file creation workload for me by several percent on ext2 & ext3.
