Subject: [Qemu-devel] [PATCH 0/2] Allocate mutiple clusters for VMDK I/O
Date: Sat, 11 Mar 2017 17:24:03 +0530	[thread overview]
Message-ID: <1489233245-27057-1-git-send-email-ashijeetacharya@gmail.com> (raw)

This series optimizes the I/O performance of VMDK driver.

Patch 1 makes the VMDK driver to allocate multiple clusters at once. Earlier
it used to allocate cluster by cluster which slowed down its performance to a
great extent.

Patch 2 changes the metadata update code to update the L2 tables for multiple
clusters at once.

Note: These changes pass all 41/41 tests suitable for VMDK driver.
