Poul-Henning> This is a problem which is in the cross-hairs for 6.x That reminds me... has anyone thought of designing the system to have more than 8 frags per block? Increasingly, for large file performance, we're pushing up the block size dramatically. This is with the assumption that large disks will contain large files. ... but I havn't seem that, myself. Large arrays that we run tend to have multiple system images (for diskless or semi-diskless operation) and many more thousands of users ... all with their usual complement of small files. It strikes me that driving the block size up (as far as 1M) and having a 256 (or so) fragments might become appropriate. We probably also need to address disks with larger block sizes soon, but that's another issue alltogether.
