fixed vs parent > child vhd ?

-

i use fixed vhd each vm because faster dynamic consumes lot's of space
 
what speed difference between using fixed vhd against parent > child vhd ?

a fixed vhd offers best performance, it's not easy provide quantitative answer because many factors come play. dynamic disks group, performance slows because of fragmentation. idea behind use of fixed vhd preallocate fixed amount of contiguous space eliminate effects of fragmentation.

 

i offer performance metrics, have been told not release metrics based on prerelease versions of hyper-v.



Windows Server  >  Hyper-V
