MirrorChunkSize Block size (in bytes) used in the mirroring process
Values:
1
-
375000
Default:
32768 (32K)
A higher block size value gives you better throughput, but only to a certain point, then it starts
using more memory because of the way memory is allocated and deallocated. A lower block size
value produces slower throughput, but uses memory efficiently. The optimal value is 32768. The
MirrorChunkSize
should not be larger than the

.
