I don’t really look at server response times too much, because generally it’s a bit dull, really. If our server is really sick then the automatic alerts and text messages from Pingdom tell me to get fixing.

Anyway, tonight I just thought I’d have a look at some graphs. And hey, there’s a bit of a shock… my own site, this one here, is getting slower. Here’s the graph:

Now, what you’ll notice is that generally everything looked nice and brisk until early August 2009 when there was a marked deterioration in performance. Then it plodded along just fine until December 2009 when it got worse again.

Is It WordPress Bloat?

I wondered what had happened to cause this – I’m especially shocked that a page load is now so slow. I haven’t changed the theme in use for at least a year, and the plugins are generally ones I use elsewhere. So I did a bit of thinking, and then it dawned on me when I found this list of release dates at WordPress.org:

The dates correlate exactly with the worsening performance of this site.

Now, correlation absolutely does not relate to causality. At upgrade time I usually take a moment to review plugins, upgrade the theme, etc. It could be that an upgrade or change to one of the many plugins in use here that has caused the slowdown. I know it’s not traffic to my site – that’s been flat for ages, with only the occasional blip. The server is a dedicated machine running about fourty sites that we manage, but the load is generally quite consistent and impact on different websites is fairly well managed.

But I’m a speed freak. I like it when a website zings into view. I love fast cars. I love computers that don’t dither. I love telephones that respond instantly. So I hate that response times are now below 1s. That’s not on!

So I’m going to try to find the cause of this slowdown – I’ll be running some experiments on this site, profiling queries, checking the database over and so on. And I’ll document it all as a way of showing you how we at Interconnect IT do our performance tuning. Whether I document it here or there I haven’t decided yet – I think it would make a good case study for the site. We’ll see! Watch both sites…

Over the weekend just gone I made two planned presentations at WordCamp UK 2009 down in Cardiff. I also threw in a quick 45 minutes of show and tell on the Caribou Theme that runs this site and is available for download from Spectacula.

I also got to mix with some very interesting, talented and cool people that know a heck of a lot of stuff about what we’re working with. In this conference were, potentially, the next generation of web creators. People who will make things happen. And this year, more than last, there was a real buzz at the potential of WordPress, its markets, and its uses.

Presenting at WordCamps

I’ve never actually done a formal presentation in front of more than about ten people before in my life, and even then only perhaps four five in my life. I’m a techie – I would do technical discussions and demos, but never with Powerpoint and a laser pointer. I did do an unconference show and tell at Barcamp Liverpool last year where about twenty to thirty people turned up, but that wasn’t planned… it just kind of happened.

But I could also appreciate the benefits of putting myself out there in front of a room full of my peers. So in a fit of enthusiasm I volunteered for two presentations – WordPress in the Enterprise, and WordPress for News and Media. I expect one or even both might be dropped by the organisers. I have no history or background in public speaking.

Both got accepted.

Damn!

But it had some great potential too. I could play with approaches and actually ‘test’ the results. So what did I learn? Read on:

1. L-Shaped Rooms are Tricky

The main room for the event turned out to be L-shaped… or, a better description, V-shaped, with the presented at the bottom of the V. At this event three rooms were in operation, a large L-shaped room with up to 150 people, a medium sized rectangular room for up to 70 people, and a small boardroom type for about 15 people.

I had expected my first presentation on the Enterprise to be the tricky one – it’s not a fascinating subject. But it was in the medium sized room, and it proved very easy to get engagement with the audience. In the L-shaped room you’re trying to look in two different directions. It’s almost impossible.

2. Consider an Assistant for Demos

One can work the computer, the other can talk. Saves awkward silences, and it’s something I’m going to try in a future talk.

3. Get in Early

I did one of the first, and the very last, formal presentations of the event. I noticed that in the first everyone was wide awake and very enthusiastic. By the end of the conference people were flagging. Getting and keeping attention becomes trickier at this stage. You also have the advantage that nobody ever wonders off from the conference at the very beginning – it’ll never be fuller!

4. Start Funny

In the Enterprise talk I started with a humorous quote and in the News & Media I started with a pithy quote. The funny one got the mood lifted and people in a cheerful mood. It gave me a chance to relax and settle into the presentation.

5. It’s a Great Audience

I was dealing with fellow geeks. People in the same situation as me. It was, frankly, the best audience I can imagine. The few presentations I’ve done before have been up in front of a board of hardened and cynical directors, or senior management, or people who have tough deadlines to meet. This was a whole lot more relaxed. Nobody’s going to consider firing you because of a minor mistake.

6. Get Engagement

I noticed that speakers who asked for shows of hands, asked questions of the audience and so on generally had a better applause at the end than those who didn’t. It doesn’t take much to engage your audience, but I’ll admit that it’s trickier when you can only look directly at half of them at any one point.

7. Be Prepared

At conferences opportunities come up. Have business cards, listen to people, smile a lot.

8. Freebies

You can’t believe how the mood of a room lifts when you hand out gifts. Good gifts though. I remember the really rubbish calculators we got given in my ICI Systems days. What geek in the world needs a calculator? So I handed out the penknives we had made for Spectacu.la and they went down a treat.

9. Matt

I finally met Matt Mullenweg at the weekend. I’d promised him a beer months ago in reconciliation following our (now seemingly minor) argument over WordPress’s take on the GPL. So I bought him a pear cider and had a good chat. He’s an affable chap, easy going, says ‘awesome’ a lot (but he’s American, so that’s normal) and has clearly listened to the concerns of WP developers about how they’ll make any money.

Funny hat tho’ ;-)

Summary

An ace time, basically. I’d like to say hi to everyone I met, but I’m scared of missing someone – so instead, let’s just say I look forward to chatting and, hopefully, working with some of you in the not so distant future.

Here’s to WordCamp UK 2010!
