...ory shows 2GB, though the two major hogs of that memory (two MySQL instances) claim to be consuming about 6.2GB (checked via pmap). Also, it seems like the ARC keeps creeping the kernel memory over the 4GB limit I set for the ARC (zfs_arc_max). What I was also, curious about, is if ZFS affects the cachelist line, or if that is just for UFS. Thank you in advance!

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, Can I use DTrace to determine memory status? 1.Total Physical Memory, Used Memory. 2.Total Swap Space and Used Swap Space. I did find few DTrace scripts but had too much in them and I am unable to chop off unwanted lines of code due to lack of knowledge. It will be very helpful if some one can share the piece of code that serves my purpose as mentioned above. Regards, Ramesh. Ramesh

Running an mmap-intensive workload on ZFS on a X4500, Solaris 10 11/06 (update 3). All file IO is mmap(file), read memory segment, unmap, close. Tweaked the arc size down via mdb to 1GB. I used that value because c_min was also 1GB, and I was not sure if c_max could be larger than c_min....Anyway, I set c_max to 1GB. After a workload run....: > arc::print -tad { . . . ffffffffc02e29e8

I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this: dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface
