That limit then depends on block size and filename lengths. for 4k blocks, and 40 char names, you max out at around 20 million directory entries, if my old spreadsheet is still correct. That limit is the same for ext3 and ext4. performance-wise, to be honest, I'm not sure. how many inodes are you talking about? -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
