What is VMOptimizer? Well, being able to run other operating systems without having to restart your Mac is undeniably useful, but over time performance can degrade which can be frustrating if you're trying to run a game. You might have been able to improve this performance by running a defragmenter such as iDefrag, but that only solves part of the problem.
Most files only suffer from one kind of file fragmentation, but virtual disks suffer from three different kinds of fragmentation which means the performance degradation caused by it is multiplied. Now it is possible to tackle each kind of fragmentation individually, but that's awkward and time consuming. Things get even more complicated when you add the fact that virtual disks are usually split into many files and they might be using snapshots.
This is where VMOptimizer steps in. It quickly and efficiently tackles all three kinds of fragmentation in one go.
VMOptimizer is also able to make other optimizations that can significantly boost performance, such as realigning partitions that happen to be misaligned.
v1.0 [Dec 28, 2011]
- Fixed support for virtual disks having names with non-English characters.
- Fixed a problem with realigning older virtual machines that use an old method of booting.
- Support newer virtual disk features that VMware Workstation can create.
- Support older virtual machines that do not specify an encoding.
- Fixed some problems where VMOptimizer would report a non-specific problem when trying to optimize a virtual disk.
- Fixed a couple of minor user interface issues.
- Fixed some issues with handling very fragmented NTFS volumes.
