Valid numbers range from 2-8 inclusive. The default value is 8 buffers for filesystems with a blocksize of 64KiB, 4 buffers for filesystems with a blocksize of 32KiB, 3 buffers for filesystems with a blocksize of 16KiB and 2 buffers for all other configurations. Increasing the number of buffers may increase performance on some workloads at the cost of the memory used for the additional log buffers and their associated control structures. Is this still valid? I thought that newer kernels would always use 8 as default? tia, Michael _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
