If there were an infinite number of developers it might be different, but there aren't. So the latest release (and -current is even better) should be used if possible. Looking at http://openbsd.org/plus54.html shows quite a few changes. --STeve Andre'

Help troubleshooting performance problem
I'm having some trouble figuring out what is causing a systemic performance issue. By "systemic" I mean that running even seemingly trivial things (i.e. 'ls' on a directory with only a few files in it) is accompanied by a substantial delay before any response, say, of 15-30 seconds. Not *every* single time, but pretty frequently. Looking at top, load average is higher than expected on a largely idle web & smtp server, usually between .7 and 1.6. This is a dual-core opteron box (Sun Fire X2100) with 8GB RAM. (dmesg below). Sorting top by CPU utilization shows that the CPUs are mostly idle. vmstat/iostat isn't making anything leap out at me as getting stuck in paging or waiting for I/O. The disc is a softraid RAID1 volume, bioctl shows that it's OK. This does not appear to be network bandwidth-related, at least, I can get the expected throughput testing with iperf. Posting something on the forum software that it's running can take 3-4 minutes to complete, and it's writing the posted info to a mysql database. Neither httpd nor mysqld seem to wind up much load while this is occurring. So, what should I be looking at to figure out where things are getting stalled up?

Re: Should Android have used OpenBSD instead of Linux?
Hi Frank, I heard this argument that OBSD is slow circulated a little bit. Can you please clarify and quantify? Really performance is of a very secondary importance, however unless there's a good reason for it not to be there, it is nice that it is there, hence my question for you to clarify and quantify now - Thanks, Mikael 2013/11/29 frantisek holop > hmm, on Tue, Nov 26, 2013 at 02:00:53PM -0800, Chris Cappuccio said that > > So the next question is, why would someone want to switch to OpenBSD > > on one of these platforms? > > > > 1.

My ALIX 2D13 works fine with 115200 - no quirks. 38400 is default but I don't think that a wrong baudrate would output anything at all except house numbers and grzmrf, especially not at high baudrates. Did you, Aurelien use a quality CF-card? That is very important. Is the power supply sound? Even the 2D3 may be defective (rarely) and e.g. PC-Engines swaps them on warranty free. Sorry I didn't upgrade to 5.4 yet. I installed OpenBSD 5.3 onto the CF-card while it was connected to a MACbook Air via a USB-adaptor and used the network install. Then I inserted the CF-card into the ALIX 2D13 and booted. No problems. See OBSD FAQ 14.17.3. Maybe Aurelien, you want to try this before you send the board back to the supplier.
