...s perform better, UFS will again gain the lead. I will now prepare the query benchmark to see how ZFS performs with a larger amount of parallelism in the database. In order to test also read throughput of ZFS vs. UFS, instead of using a larger dataset I will cut the memory the OS uses by setting physmem to 1GB. -- Daniel

...marking at a customer (using IOzone) and for some specific small block random tests, performance of their X4500 is very poor (~1.2 MB/s aggregate throughput for a 5+1 RAIDZ). Specifically, the test is the IOzone multithreaded throughput test of an 8GB file size and 8KB record size, with the server physmem''d to 2GB. I noticed a couple of peculiar anomalies when investigating the slow results. I am wondering if Sun has any best practices, tips for optimizing small block random I/O on ZFS, or any other documents that might explain what we''re seeing and give us guidance on how to...

I just installed build 41 of Nevada on a SunBlade 1500 with 2GB of ram. I wanted to check out zfs since the delay of S10U2 I really could not wait any longer :) I installed it on my system and created a zpool out of an approximately 40GB disk slice. I then wanted to build a version of thunderbird that contains a local patch that we like. So I download the source tar ball. I try to untar it on the

kernfs seems to have disappeared between 4.7-REL and 4.8-REL, but I couldn't find any mention of this in any of 4.8-REL docs, where/why did it go? -Paul-

Hello. We''re currently using a Sun Blade1000 (2x750MHz, 1G ram, 2x160MB/s mpt scsi buses, skge GigE network) as a NFS backend with ZFS for distribution of free software like Debian (cdimage.debian.org, ftp.se.debian.org) and have run into some performance issues. We are running SX snv_48 and have run with a raidz2 with 7x300G for a while now, just added another 7x300G raidz2 today but

Hi, I try to use lm to fit a linear model with 600k rows and 70 attributes. But I can't even load the data into the R environment. The error message says the vector memory is used up. Is there anyone having experience with large datasets in R? (I bet) Please advise. thanks, Yun-Fang [[alternative HTML version deleted]]

Hello, freebsd-stable. Does somebody use some software RAID5 on FreeBSD in real production system? I want to build storage server for my home: RAW photos, multi-layer PhotoShop files and FLAC-encoded music consume a lot of space, and they should be availible both from desktop & notebook. Also, all photo-content is unique, so I need some insuranse from single HDD crash. I understand,

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's
