Dillsmack went to Italy for a bit so I am playing with code on my own. (expect downtime). Anyway I been playing with magpierss, wp-cache, and memcached and woah.
The Wu-Tang clan knew what they were talking about with C.R.E.A.M
EDIT:
Here is an example of my code for the top commentors on the side bar that I wrote and the memcache that caches in information:
PHP:
-
function posse()
-
{
-
#start cache
-
$cache_key = "posse";
-
$memcache = new Memcache;
-
$memcache->addServer('127.0.0.1', 11211,0,1,1,1);
-
$output = $memcache->get($cache_key);
-
if (!$output) {
-
#end Start Cache
-
-
-
-
print "<div class=\"topcom_body\">";
-
-
$commenters = $wpdb->get_results("SELECT COUNT(comment_author) AS commentcount, comment_author, comment_author_url FROM $tablecomments
-
WHERE unix_timestamp(comment_date)>unix_timestamp(NOW())-(60*60*24*7)
-
AND comment_author_url !=''
-
AND comment_author !='ShoeMoney'
-
AND comment_author != 'ddn'
-
AND comment_approved = '1'
-
AND comment_type =''
-
GROUP BY comment_author
-
ORDER BY commentcount DESC
-
LIMIT 20;");
-
-
foreach($commenters as $commenter)
-
{
-
-
print " <div class=\"topcom_row\"><a href=\"".$commenter->comment_author_url."\" class=\"topcom\">" .stripslashes($commenter->comment_author)." ($commenter->commentcount) </a></div>";
-
-
-
}
-
-
print "</div>";
-
-
#End of Cache Code
-
$memcache->set($cache_key, $output, false, 60); // 60 second cache
-
} else {
-
echo $output;
-
return;
-
}
-
#End of Cache Code
-
-
}
So for those who understand php you can see this would be a pretty huge load for the 65,000+** hits this recieves a day... but by caching this for 60 seconds you drastically lower that 
Cacheing rocks!
**hits refers to total pageloads not unique visitors. This site only gets between 10,000 and 15,000 unqiues per day

This is very true… cache rules after all
I was going to mention you might get stale comments, but I see the cache is cleared every 60 seconds, not every 60 minutes. I guess that’s a good compromise
Good idea
I’m using BlogEngine.net which is ASP.NET, which it has built in support for “output caching” that basically does the same thing. You can specify a timeout, and a querystring parameter used to decide whether the cache is unique (eg. if you have ?postId=x you want the cache to very with x).
Me too!
Wp-Cache must be a default plugin for wordpress actually.
BTW Excellent idea you gave . I would like to try on my blog too
better to be over prepared and cautious than caught with your pants down and loose traffic possibilities.
Same here, I’ll be giving memcache a go this weekend, looking forward to tracking performance results
No one said it was better, he said it was “simpler”.
wp-cache: You have the influence to get WP to add this feature. I might get a form letter response, but you could probably get them on the phone.
Thanks for the code, I’ve never used memcache before (my traffice levels aren’t as high as yours so never been spurred to go past wp-cache) so thanks.
Wp-Cache is really great wordpress plugin , as u said for big sites this plugin is really mandetary.I hope wordpress fucture versions will have Wp-Cache as default plugin.
You are totally wrong. uniques is no measure.
Ever been dugg? I guess not. Get 150+ hits a second and let me know how that goes.
IMO, cache-ing is not justified for a website with less than 30k uniques. It does free some resources, but with nowadays servers, it takes a lot of traffic to to intimidate them. Smarty introduced such a cache-ing tool a long time ago, but I fail to see the the point of it, unless the server really can’t handle the requests. Just my opinion, I may be wrong
Thanks for this Shoe. You’ve inspired me to give WP-Cache and magpie a shot.
Like everyone else I can’t figure out why this isn’t included in Wordpress already.
You should take a look at SimplePie for that RSS Stuff
dollah dollah bill y’all.
Damn now it’s stuck in my head.
thats pretty awesome man!
I think the version with Mary J Blige is best.
lol great Wu Tang reference
I have Magpie running on my blog too… but not like you!
I had some issues with wp-cache, and I kind of am concerned about using it again because my site is updated so much I dont want my users to miss updates just because of the cache. Not sure what I can do about that..
the logo is a background image, but there’s a huge gap to the left of the banner where he could put a big box with a javascript link.
and this is the best blog post title of 2007. contest over.
Haha. Love that title. Notorious S.H.O.E
I agree with Travel Notebook. The “home” button is a few inches away, but it has just become second nature for me to click on the logo to go back to the homepage. =D
There are a million tutorials online for PHP. Just Google “PHP Tutorials” and follow along.
If you don’t like written tutorials you can check out the videos at…
http://www.phpvideotutorials.com/
or
http://www.lynda.com/ – I think it’s about $25 per month.
Probably not but i will see
just vim
Do you use a program to edit your PHP coding?
I got in the habit of using double quotes just so I can use non literal strings. I honestly have no clue if single quotes are faster then double quotes.
Shoe, is there a reason why you are using double quote marks instead of single marks in that code? I always thought single quote marks were faster.
Shoe get the money dollar dollar bills yall
Side note: Can you please make your logo clickable to the index page again? This is a standard usability thing
That’s pretty badass. How did you get into PHP and learn it?
I’d love to but I (kind of like you) resort to a friend for PHP help. Anyone else with ideas on how they learned?
Travel Permit?
Ive been meaning to look into memcached since you talked about it last time. I guess I will give it a go
I installed wp-cache but it made all of my dynamic sidebar items static. Any idea what I did wrong? I’m decently tech-savvy but I admittedly didn’t look into it very far before de-activating it.
Did Dillsmack allow you to play with code?
I lovvvve wp-cache, it’s drastically sped up my WP sites
playing with it. its entertaining… for now
Maybe it will last longer then mybloglog
Yea. This is the install steps:
1. Upload the folder.
(Unless you have some permissions you need to set)
2. Click activate.
3. Done.
shoe is twittering??? I’m wondering why? Do you have a custom app in the works since they opened up their platform to developers?
… “get dat money” (SHOE!) “dolla dolla bill y’alllllllllll” :p
So basically you’re saying.. start using wp-cache and your site will live through moderate digging??? Any wordpress site on it’s own box basically?? I think I’ll have to start learning as well :S
I stop reading at “Dillsmack went to Italy for a bit”… I’m still waiting my travel permit and I already bought $2000 in tickets to go visit my family in Italy with my wife and probably I won’t be able to go
*sigh*
C.R.E.A.M brings back memories…Wu Tang Clan is off the hook…ha ha
Thanks a bunch.
sure I will edit the post with a example
Care to share the memcached code? A lot of wordpress users could benefit from this
Why is Last RSS better than magpie?
What other plugins do you use Paul?
V
I use WP-Cache and didn’t even realize that there were other options. Though this plug in works very well for me, it’s nice to know that it isn’t the only plug in available.
nope… you just have to create a cache folder. The directions are pretty straight forward.
I also use wp-cache, and while it has issues with certain plugins with dynamic content (such as wp-postratings), it is indeed very handy to keep installed in the event of a slashdotting or getting linked from boing boing. I agree that wordpress needs to just integrate this into the main system.
Does wp-cache require anything extra server side? I see a lot of posts on google saying they have problems installing it. I have not personally tried it myself yet, but I will bookmark this page for when I start a blog.
Very interesting, i am planning on trying MagPie.
Last RSS is a good alternative to magpie if you want something simpler.
Since im using the wp-cache, I just can’t live without it! It makes my page faster and with the load of traffics from stumbleUpon, my blog is still on!
Looks great. I think I’ll take a look at Wp-Cache for my own blog. Thanks for the recommends.
