I have a filesystem with an external log where I've increase logbufs to 8 and also the size to 256k. With this I see *much* better performance for somethings like cp -Rl and rm, but not reliably... there are times when the performance is worse. It's not clear how to choose sensible values other than by trial and error. --cw |
