It is the libsvm default:
-e epsilon : set tolerance of termination criterion (default 0.001)
from http://www.csie.ntu.edu.tw/~cjlin/libsvm/
Larger cache size doesn't hurt, but I'd be surprised if you have runtime
issues on many UCI datasets.

I’m using datasets from UCI, hence, fairly small.
1.Should I change cache_size? I’m not sure how to relate this to the
dataset size.
2.How should I set the tolerance of SVM? With rbf SVM I notice that
sometimes the error increases if the tolerance is too small, for
example, 1e-7, which is the Matlab default. How was 1e-3 determined?
Thank you,
