comment I'm seeing performance problems with postfix accepting mail when the queue is already large, any suggestions?
I have found over the years people tend to think in terms of their situation and have a hard time imagining anybody else's life being any different. Such is being human.

comment How can I force xenserver to create a full (not paravirtualized) vm?
Apologies, I jumped the gun. But soooo many times in my life, when I ask for help I run into the problem of people who want to help me their way instead of trying to help me my way. And I understand that there are situations where I need somebody to point out a solution outside the box I'm thinking in, and since as you point out, I did not make that clear, your comment is not unreasonable.

Fair enough. I concede. That's a reasonable explanation. Thanks.

The answer is "because I am building software and I need to be able to test it on many platforms that my users will be using." Now my question to you is: Why are there so many people who would rather tell you what you're doing is wrong, rather than try and answer your question?

comment LVM Performance overhead?
Did I mention reading, from a mirror? Should have gone faster than the plain ext4 disk.

comment LVM Performance overhead?
I dunno, my experience with lvm isn't that impressive. I ran a little test, I put a 70 gig image on a raw ext4 volume and the same 70 gig image on an lvm 2 disk mirror formatted to ext4. Same machine same exact disks. I then dd'd the image to /dev/null, it took 6 minutes 9 seconds to read from ext4 and 16 minutes 1 second to read from the mirror. That's READing.

comment ZFS: Best-practices doc state: “On systems with 1,000s of ZFS file systems…”?
Thanks for the reply, are there any known limitations or documentation on where it starts to fall apart? Lots of filesystems? Lots of files in a few filesystems? Millions of snapshots on large filesystems? Anything like that?

right, so given this situation given enough disk can zol handle 10s of thousands of filesystems? it is very memory intensive?
