New homepage!

Yeah, I don't know why, but it's work for me now.

Hi guys...

Um.
That was me.
Ngaytxoa.

I was playing with how much of the WordPress caching I could offload to APC and I think it peed itself or something. Anyway, I backed off a few of the test changes and it seems to work now. Please let me know if the garbage comes back.

Seems it works normally now. Thanks for putting it back to rails

I actually have managed (I think) to optimize WordPress a bit, so hopefully everything is happy.

In case anyone is wondering why I am fooling with a lot of tuning stuff, it is because with 32GB of RAM to play with now, I am setting the server up for huge crowds when AVTR2 starts to ramp up. I know it is a ways off yet, but no use waiting around!

Meh, at that time we maybe will have new server again

Toruk Makto · February 01, 2013, 02:06:10 PM

Good heavens, I hope not. The one we have is a friggin bulldog. The next upgrade for it will be to replace the SATA hard disks with SAS 6Gb drives and set up a ZFS array. Probably around the end of this year.

Load sharing web server farm?

Irtaviš Ačankif · February 01, 2013, 02:28:52 PM

From my experience https://www.cloudflare.com/ seriously reduces load on resource-heavy websites and also makes sites a bit faster. Handled a medium-traffic site on a bleeeep'in netbook on DSL with thousands of hits per day without issue with it. Without it, don't mention how my box struggled...

Also at least before I headed to Canada, LearnNa'vi was getting heavily packet-inspected from the Chinese firewall, slowing it down immensely. Moving to CloudFlare could fix that since tons of sites have CloudFlare IPs.

All in all with CloudFlare on, my current tiny VPS can take 500 concurrent users pulling 20 MiB/s constantly (by Loadimpact) with completely negligible drop in performance or even rise in load average. I usually won't worry about the Slashdot effect with CF on, though perhaps other things might be messier (getting user IPs needs a lighttpd module)

I think Seabass has looked at that before. It is a seriously cool service. The problem is that most of our content is dynamic, since most traffic comes from the forum.

(enulating Norm) ZFS?? Yes!!

ZFS...Eywa tested, Eywa approved!

Hmm. So generally CPU is the limiting factor, not the bandwidth coming from the repeated loading of avatars, csses, etc?

Toruk Makto · February 01, 2013, 09:56:54 PM

No, just that CDN services work better on static content. We have a boatload of CPU headroom and RAM for caching, so I am not worried about outrunning the server. That said, I have put the WordPress main site back up on cloudflare to see how well it works. That should help on bandwidth since we exist on a 95th percentile plan that could get expensive if the sustained demand exceeded 10Mb for a month.

Only downside is that you have to build the fs from scratch and spool in from backups. Not a huge hairy deal, just it would have the site down for most of a day.

I guess it depends on how much of the filesystem you put on ZFS. I know ZFS is more BSD-friendly than Linux-friendly. I just keep bulk storage on ZFS, and ext4 for the boot and home drives. As I get more comfortable with ZFS, I will move more of the system over to it. I have a server/scientific computing grade 1TB WD velociraptor drive for boot and home. That drive is noticeably faster than any hard drive I have ever used. It is worth every cent of its premium cost.

As far as I am concerned, having your very own server is far better than any cloud-based service!

ZFS is indeed a great filesystem, it was used by default for solaris and OpenSolaris. I guess OpenIndiana still uses it by default.
