The directories themselves will have a maximum of 160 files, and the files are maybe a few megs each - the delays are (as you pointed out earlier) due to the ram restrictions and our filesystem design of very deep directory structures that Netapps suck at. My point is more generic though - I will come up with ways to handle this problem in my application (probably with threads), but I'm griping more about the lack of a kernel interface that would have allowed me to avoid this. -Aaron - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
