Re: IDE or SCSI virtual disks for VMWare image?
Any word on the degraded performance of fork operations inside the vmware server guest? Or am I imagining that thread of e-mails? ~BAS On Sat, 2007-07-07 at 10:04 -0500, Todd Pytel wrote: > On Sat, 2007-07-07 at 10:44 -0400, Nick Holland wrote: > > > There's the answer to your question: For your app, it just won't matter. > > You've spent more time asking, and others (including myself) have spent

I'm sorry for wasting your time. I thought it was a fairly simple question - more like "Is one of the options drastically better or more stable than the other?", not "How can I can get an extra 1% on a synthetic benchmark?" Since there's not exactly a tremendous amount of detailed information on OpenBSD in VMWare beyond just setting it up, I asked here because I figured some people had more experience and could answer the question quickly, as they did - the disk type doesn't matter. That answers my question just fine. Thank you all for your responses and your time. --Todd

You've spent more time asking, and others (including myself) have spent more time answering your question than you will ever personally benefit (i.e., more work done at the end of the day/week/month). Optimizing for a 1% or even a 20% performance difference is rarely worth the effort for "end-of-day" productivity (major exception: when it is part of a number of other 20% optimizations. Another major exception is when you are really close to the limit for something, but then, you generally need to be working out a better strategy, not getting just barely getting by a little longer). If you honestly believe you will benefit from such an optimization, you can and need to do your own benchmarks. There are just too many variables in your question to be asked and answered in the way you asked it. For example: * VMware version * VMware host hardware * Other system load * OpenBSD load * etc... Practically speaking, if you are worried about performance, you probably don't want to be in a virtualization environment. If you are trying to optimize for the sake of optimizing, there are probably a lot better ways of spending your (and our!) time. Nick.

IDE or SCSI virtual disks for VMWare image?
I'm going to be running a few OpenBSD virtual machines and was wondering whether there was any performance difference between using IDE or SCSI virtual disks. From what I can tell, the SCSI option has been supported longer, though IDE has also been stable for a while now. But I haven't seen any comments on performance differences, if any exist. If it matters, this is going to be lightweight, home server kind of stuff. Thanks.
