[Qemu-devel] [PATCH 1/2] vmdk: Optimize I/O by allocating multiple clusters

2017-03-11 Thread Ashijeet Acharya

The vmdk driver in block/vmdk.c used to allocate cluster by cluster which slowed down its I/O performance. Make vmdk driver allocate multiple clusters at once to reduce the overhead costs of multiple separate cluster allocation calls. The number of clusters allocated at once depends on the L2
