Test & Evaluation

If the file system is to have any success, then the overhead introduced by its implementation on top of TACO and the existing UNIX system should be negligible. I have made a series of tests to measure the overhead (in time).

I have not performed any thorough black-box or internal test, but I do think that the performance tests cover most cases: strict, optimistic, and pessimistic read and write operations, fully connected, weakly connected, and disconnected mode, cached and not cached!

The performance tests are described in Section 7.1, the results are listed in Section 7.2, and an evaluation is made in Section 7.3. The evaluation section also lists problems encountered with using $\mathcal{P}$$e$$\mathcal{S}$$t$$\mathcal{O}$ and TACO.
