If only creating a few Snapshots running at the same time then performance will not be an issue. Link below from our Knowledge Base on Snapshots.

The total number of snapshots is dependent on the LVM, but 255 is a safe
number. There are, however, definite limitations as to the number of ACTIVE
snapshots:

32bit system:
- 10 per LV
- 20 per system

64bit system:
- 1 per LV
- 10 per system
