Hello, I was doing performance testing, validating zvol performance in particularly, and found that zvol write performance to be slow ~35-44MB/s at 1MB blocksize writes. I then tested the underlying zfs file system with the same test and got 121MB/s. Is there any way to fix this? I really would like to have compatible performance between the zfs filesystem and the zfs zvols. # first test is a file test at the root of the zpool vg_satabe...

Also we rely more on linker dead stripping with ThinLTO. On MacOS it works well with the atom model, on ELF I’d expect the LTO equivalent of -ffunction-sections to be used (I don’t k...

On Unix systems these are all symlinks and so essentially free. I hear Windows doesn't cope well with that

Right, though usually the chance to do complete whole program optimization provides enough opportunities for it to go the other way. Of course, it can al...

I just built a stage-1 compiler from the 3.9 release bits and built the lldb from head sources which worked fine. Let me try again using 3.9 build compiler to build 3.9 bits.

Hi list, I am trying to install FreeBSD 9.1-Release amd64 on a Supermicro server: SuperStorage Server 6027R-E1R12N with Intel Xeon E5-2640 CPU and 32 GB (4 x 8 ) KVR16R11D4/8HC installed Currently I have only 2 SSD Kingston drives (working in mirror) installed on that server. during booting installer from the ISO CD (amd64), the boot process fails with message: Mounting from

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many

Hi! I've installed Solaris 10 x86 (Core2Duo - x64) server, with Samba over ZFS RAID-Z. Samba is a part of Active Directory Domain. I've managed to join it to domain, to get the users and groups from A.D. and to translate them to Unix IDs. Everything works really good. Samba is installed from the packages from Solaris 10 DVD. Only problem I have is the performance :( It's
