The number of files within a LUN has less direct impact on block-level snapshot performance than the actual rate and volume of data block changes, which relates more to LUN size.

The number of LUNs affects the total snapshot workload, but it does not directly influence the time-to-create or incremental update performance for a single copy-on-write snapshot on a specific LUN.

The size of the snap volume (the allocated space for snapshot data) determines how many changes a snapshot can track, but it's not the primary factor affecting the instantaneous creation time or the performance of the incremental copy-on-write operations themselves.

Although the initial creation of a copy-on-write (CoW) snapshot is nearly instantaneous by only creating metadata, the ongoing incremental updates are directly affected by the size of the LUN. When data changes on the original LUN, the old blocks are copied to a snapshot reserve area before being overwritten. A larger LUN means potentially more data blocks that can change, requiring more data to be copied and managed, thus impacting the efficiency and resource consumption of the snapshot process over time.
