Greeting All I am using Filebench benchmark in an "Interactive mode" to test ZFS performance with randomread wordload. My Filebench setting & run results are as follwos ------------------------------------------------------------------------------------------ filebench> set $filesize=5g filebench> set $dir=/hdd/...

...busy with some tests on the above hardware and will post some scores soon. For those that do _not_ have the above available for tests, I''m open to suggestions on potential configs that I could run for you. Pop me a mail if you want something specific _or_ you have suggestions concerning filebench (varmail) config setup. Cheers This message posted from opensolaris.org

HI, The question is a ZFS performance question in reguards to SAN traffic. We are trying to benchmark ZFS vx VxFS file systems and I get the following performance results. Test Setup: Solaris 10: 11/06 Dual port Qlogic HBA with SFCSM (for ZFS) and DMP (of VxFS) Sun Fire v490 server LSI Raid 3994 on backend ZFS Record Size: 128KB (default) VxFS Block Size: 8KB(default) The only thing

I have been testing the performance of zfs vs. ufs using filebench. The setup is a v240, 4GB RAM, 2 at 1503MHz, 1 320GB _SAN_ attached LUN, and using a ZFS mirrored root disk. Our SAN is a top notch NVRAM based SAN. There are lots of discussions using ZFS with SAN based storage.. and it seems ZFS is designed to perform best with dumb disk (JBODs). The test I r...

I have setup a distributed glusterfs volume with 3 servers. the network is 1GbE, i get filebench test with a client. refer to this link: https://s3.amazonaws.com/aws001/guided_trek/Performance_in_a_Gluster_Systemv6F.pdf the more server for gluster, more throughput should gain. I have tested the network, the bandwidth is 117 MB/s, so when i have 3 servers i should gain about 300 MB/s (3*11...

Can anybody tell me how to measure the raw performance of a new system I''m putting together? I''d like to know what it''s capable of in terms of IOPS and raw throughput to the disks. I''ve seen Richard''s raidoptimiser program, but I''ve only seen results for random read iops performance, and I''m particularly interested in write

Hello, I have been experimenting with ZFS on a test box, preparing to present it to management. One thing I cannot test right now is our real-world application load. We write to CIFS shares currently in small files. We write about 250,000 files a day, in various sizes (1KB to 500MB). Some directories get a lot of individual files (sometimes 50,000 or more) in a single directory. We spoke to a Sun

I''m looking at the newly-orderable (via Sun) STEC Zeus SSDs, and they''re outrageously priced. http://www.stec-inc.com/product/zeusssd.php I just looked at the Intel X25-E series, and they look comparable in performance. At about 20% of the cost. http://www.intel.com/design/flash/nand/extreme/index.htm Can anyone enlighten me as to any possible difference between an STEC

...th kmem_zalloc(). According to the overhead caused by tsd_get() and tsd_set(), I did an experiment to measure it. In this experiment, I run a dtrace script to enable nfsv3client probes and measure time consumed by each nfsv3 operation and tsd_get() and tsd_get(). Then I run some workloads in *filebench* to perform some file operations in a nfs mounted folder. I use the ratio of time spent on sd_get()+tsd_get() to the time spent on the whole operation to evaluate the overhead. The workload I selected are: randomrw, filemicro_rwrite, filemicro_rread, randomread, randomwrite. Summary of the...
