Well, I haven't had any problems implementing the kind of processing I've
been doing. I wrote a utility to scan through a directory structure and
compute SHA1 hashes of all of the files. When implemented smartly, it
spends about 97% of its time in the SHA1 hash computation (A C library),
so does't really have much different of an overhead of one written in a
less pleasant language.
Written with lazy lists, and a Haskell SHA1 is is hundreds of times slower.
I don't think Haskell will be a barrier to writing something like backup
software, as long as it is possible to hand the data around in chunks.
