Compile Saba with AIO support, load the aio.ko if not yet done and set the following sysctl values:


kern.ipc.maxsockbuf=16777216
kern.ipc.nmbclusters=32768
kern.ipc.somaxconn=32768
kern.maxfiles=65536
kern.maxfilesperproc=32768
kern.maxvnodes=800000
net.inet.tcp.delayed_ack=0
net.inet.tcp.inflight.enable=0
net.inet.tcp.path_mtu_discovery=0
net.inet.tcp.recvbuf_auto=1
net.inet.tcp.recvbuf_inc=524288
net.inet.tcp.recvbuf_max=16777216
net.inet.tcp.recvspace=65536
net.inet.tcp.rfc1323=1
net.inet.tcp.sendbuf_auto=1
net.inet.tcp.sendbuf_inc=524288
net.inet.tcp.sendspace=65536
net.inet.udp.maxdgram=57344
net.inet.udp.recvspace=65536
net.local.stream.recvspace=65536
net.inet.tcp.sendbuf_max=16777216
net.inet.tcp.mssdflt=1460


Additionally, set the following in the global section of smb.conf:

use sendfile = yes
strict locking = no
min receivefile size = 131072
aio read size = 1


Try the following for better write performance:

aio write size = 1


I woke up this morning at 6AM and it was white outside. Apparently it was snowing during the night. It wasn’t much, just enough to cover cover the world with a white blanket…

What surprised me a bit more was the fact that the temperature dropped to -12.5°C. Yesterday morning we had already -7°C and I didn’t think it would get much colder. There’s some more snow foreseen for today, but they say it will get warmer again beginning of next week.

Another green Christmas, I guess…

Today we had the first snow for this year. Of course it wasn’t a lot, and it’s all gone again already, but at least it was snowing a little. I hope that there’ll be more snow in the next days. I’m so fed up of warm and rainy winters.

After the latest Mac OS X upgrades, PHP wasn’t working properly any more and the blog software choked on it. I could write new posts and they would even end up in the database backend, but they would never show up. Some investigation showed that the PHP developers introduced a regression in the date function of PHP 5.2.10, causing the year to be always 0000 on big-endian CPUs like the one in this little iMac. The problem was fixed in PHP 5.2.11, and after waiting to no avail for Apple to come up with a patch incorporating this fix, I finally decided to replace PHP by one I compiled on my own. Not sure if it breaks anything else, but at least the blog works again.

…with what he says.

Today in my mailbox at work:

How to save energy and enhance your efficiency?
According to some studies, 2% of the green house gaz are caused by the use of IT technologies.

How can you make a difference?
Simply by reducing the size of your e-mails.

Words fail me…

“Kumo”, or “Cloud” in English — the best game you never heard of. If you want to see something different from your usual action-ladden first-person-shooter, then try this for a change. I promise you, it’s one awesome game. Slow, but highly addictive (but in a good way. I dare say that this is one of the few games you’ll never get tired of). When I first played it, I was immediately reminded of Windy Tales, which I watched a while ago. Both are slow, even meditative at times, both deal with winds and clouds, both create the same peace of mind inside me.

It’s available here for free. Take a look around at the website, and be sure to check out the “Extra Downloads” which are hidden behind the “Community” link, especially the soundtrack, which is amazing.

I’m always amazed how well Solaris can handle heavy load:

# uptime
8:09am up 111 day(s), 4:08, 5 users, load average: 3293.29, 2549.46, 2400.75

Yes, the server is still running fine and, albeit a bit slow, still responsive. Want to try that with your generic Intel/Linux box? Good luck.

Sorry for writing so little during the last weeks, but work and my private life are keeping me busy. I know it’s been 2 months since the last entry, but there are more important things than blogging, you know.

Being an occasional SecondLife player, I was pointed at a video from Bruce Branit and found it impressive enough to share it here. Don’t know if you can appreciate it without ever having played or at least seen SecondLife, though. Nevertheless, it’s worth watching it for its story alone. Enjoy it!

You can find a version of higher quality and resolution here on Vimeo.

I’m not yet sure if I should be happy or sad about it.
