is it bad to output many files to the same directory in unix/linux? I run thousands of jobs on a cluster and each outputs a file, to one directory. The upper bound here is around ~50,000 files. Can IO be limited in speed in light of this? If so, does the problem go away with a nested directory structure?

Thanks.
