...al performance gain comparing to their existing systems. However the outputs of the I/O stress test with iozone show the mixed results as follows: * The read performance sharply degrades (almost down to 1/20, i.e from 2,000,000 down to 100,000) when the file sizes are larger than 256KBytes. * The write performance remains good (roughly 1,000,000) even with the file sizes larger than 100MBytes. The NFS/ZFS server configuraion and the test environment is briefed as * The ZFS pool for NFS is composed of the 6 disks in stripping with one on each SATA controller....

Hi all, I am in the thinking phase of Vorbis 'file' to 'buffer' conversion. ie, accessing the stream data from the static buffer, rather than accessing the file from the decoder( the way it is implemented in the vorbis decoder). I am putting my understanding and the respective query below, As the general convention , there are two methods by which i can do this. 1) Assume what

...39;'s very slow on UFS for large buffers - effectively linear with the number of pages crossed, or about 6ms per 8KBytes on an otherwise idle SCSI disk on SPARC. The good news is that this is very fast on ZFS - on the same disk, about 7ms constant for up to 64KBytes, and about 20ms constant for 256KBytes. However this is still a bit slower than the msync(3C) approach on UFS] Thanks in advance. -- Philip Beevers mailto:philip.beevers at ntlworld.com
