- Speed: ClearCase dynamic and snapshot views are slower than local filesystems, even with good network infrastructure. Repeated subsequent builds may run dramatically faster, due to build avoidance using ClearCase's make substitute. Because MVFS requires server access every time a file is accessed, the performance of the file system depends on server capacity.
- Sensitivity to network problems: Because MVFS is essentially an online file system, failures of the server or network render the dynamic views unavailable. Offline access to the MVFS requires working in a snapshot view. A snapshot view may be created with an identical configuration specification. If the view data for dynamic views is stored on a client host (as may be done for performance reasons or to reduce the need for servers), ClearCase does not automatically handle host IP address changes.

Famous quotes containing the word weaknesses:
“You will find that reason, which always ought to direct mankind, seldom does; but that passions and weaknesses commonly usurp its seat, and rule in its stead.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Like most vigorous-minded men, seeing that there was no stopping-place between dogma and negation, he preferred to accept dogma. Of all weaknesses he most disliked timed and half-hearted faith. He would rather have jumped at once to Strong’s pure denial, than yield an inch to the argument that a mystery was to be paltered with because it could not be explained.”
—Henry Brooks Adams (1838–1918)
“Once we know our weaknesses they cease to do us any harm.”
—G.C. (Georg Christoph)
