Μια από τις προκλήσεις με ιστοσελίδας διατηρεί έναν αποδεκτό χρόνο φορτίων ενώ ακόμα έχοντας αρκετό αμέσως επιδειχθε'ν περιεχόμενο για να κρατήσει το συγκεκριμένο φορέα σας ενδιαφερόμενο. Όταν το Ι φόρτωσε αρχικά Wordpress ως προτιμημένο blogging πίσω τέλος μου και προχώρησε να προσαρμόσει το θέμα, φορτώνει όλα τα widgets, προσθέτει μια στοά φωτογραφιών, μερικές που διαφημίζουν… παίρνετε την εικόνα, πρότυπα Wordpress blog, ήμουν απληροφόρητος το blog μου είχα γίνει slooooow .....

Είναι ενδιαφέρον ότι όπως εργάζεστε στο θέμα blogs σας για να το πάρετε ακριβώς σωστό γίνεστε πραγματικά απληροφόρητοι ότι το blog σας έχει γίνει τόσο αργό που οι άνθρωποι φεύγουν πιθανώς προτού να τελειώσει η σελίδα. Το πίσω τέλος γίνεται επίσης frustratingly αργό, παίρνει γενικά κάποιο για να το σας φέρει σε προσοχή, προτού να συνειδητοποιήσετε ότι είναι ένα ζήτημα.

Αυτό υπέπεσε αρχικά στην αντίληψή μου κοντά Surgey από γειά σου τα τέρατα. Στην πραγματικότητα το blog μου διαρκούσε πάνω από 10 δευτερόλεπτα στο φορτίο που μετά από να γίνω ενήμερος από το αποφάσισα την ανάγκη Ι να λάβω μέτρα.

Εντάξει, τώρα ξέρω ότι τι το πρόβλημα είναι πώς πηγαίνω για τον καθορισμό του; Καλά έχω βρεί μερικούς εύκολους τρόπους να επιταχύνω το Wordpress σας blog χωρίς απαίτηση οποιασδήποτε πρόσθετης ικανότητας και μπορώ να γίνω πολύ εύκολα και γρήγορα.

Το πρώτα αυτό που έκανα επρόκειτο να εγκαταστήσει Firebug Firefox Plugin . Εάν δεν χρησιμοποιείτε Firefox προτείνω ότι του δίνετε μια δοκιμή. Με το Firebug plugin μπορείτε να δείτε πολύ γρήγορα πόσο μακρύς κάθε μέρος ιστοσελίδας σας παίρνετε στο φορτίο.

Firebug

Επάνω στην έρευνα παρατήρησα ότι μια δέσμη των plugins φορτωνόταν ακόμα κι αν δεν δραστηριοποιήθηκαν στο χρόνο blog μου… hmmm… να καθαρίσω επάνω τα αχρησιμοποίητα plugins. Τι έκανα φόρτωνε ένα plugin, δοκιμή, αποφασίζοντας δεν το συμπάθησα και απενεργοποιώ. Πρέπει να έχω διαγράψει επίσης το plugin δεδομένου ότι αυτό είναι μια σημαντική αιτία της επιβράδυνσης στο Wordpress blogs. Έτσι διαγράψτε όλα τα αχρησιμοποίητα widgets από plugin τον κατάλογο Wordpress σας.

Η δεύτερη αιτία των επιβραδύνσεων που παρατήρησα ήταν κείμενο widgets που δεν ήταν σε λειτουργία αλλά περιείχε τον κώδικα. Έτσι για όλα τα αχρησιμοποίητα widgets που μπορούν να δεχτούν τον κώδικα, να σιγουρευτεί είναι κενοί ειδάλλως αυτοί παίρνουν επεξεργασμένοι και επιβραδύνουν τη φόρτωση σελίδων.

Το αρκετά εύκολο δικαίωμα… αλλά αυτό δεν είναι ήταν αυτό σταμάτησε για με. Although with the two simple changes above reaping great rewards I still wanted to bring the load times down further. As a programmer I know the importance of Cache, so I found a nice Wordpress plugin that gives server side caching functionality, Wp Super Cache. Not only was the name catchy it did actually reduce load times and didn’t require the reader to do anything.

Ok, were still on some pretty easy stuff here and if everybody followed the above recommendations then your blog would definitely load faster.

Now it’s nearly unavoidable to rely on external resources to provide some form of content on your blog, i.e. adsense, mybloglog, adtoll… etc.. etc.. the list goes on.

So how do you optimize these? One strategy is to make sure your content loads before the external links, so one thing I did was put the mybloglog code in the footer.php. Now this may be beyond some peoples ability so be careful. The advantage I have with the mybloglog in the footer is that my blog loads before all the little mybloglog thumbnails have completed loading, and I have a lot of them!

Now generally blogs have some some advertising, so there are two things you can easily do here. Make sure images include height and width attributes. This will allow the browser to allocate the image space before the image is loaded, and for code based advertising place the code in an iFrame so your page continues to load regardless of what the iframe is doing. Both these tips are very effective.

Now it appears that the average persons ability to wait for a page to load is 8-10 seconds, anything longer and you risk losing your audience, and with the above tips hopefully your blog will load it’s main content within this time frame.

There is one more tip I have but this is not for the faint of heart. You can compress your .css files to reduce data that needs to be loaded. Now .css files are beautifully formatted so they are man readable, but your web browser doesn’t care, so you can save up to 30% of load times for .css files by removing all the lovely spaces, pagination, tabbing etc in the .css files that make them man readable. There a many utilities to compress your .css files and give reports on how much the file size is reduced. e.g. Icey. As I said this is not for everyone though.

I hope you can all reduce load times and feel free to leave more tips in the comments for all to learn.

Have a Safe and Happy New Year.

  1. Nice tips, Paul.

    I use YSlow myself and as you know, I’m thinking of redoing my blog design as well… it just seems so… blah.

    I also read on Yahoo Developer Network about Best Practices for Speeding up Your Web Site. I would love, love to design my own blog template but geez, too much on my plate. I’d probably get the book too if I ever decide to do it.

  2. yeah, I agree with making our own templates to get exactly what we want..but no time, so much beer and only one mouth ;-) Thanks for the link, maybe I can squeeze some more speed.. and of course share with the community.

  3. Can ICEY compress ANY HTML type files? If you don’t compress on blogspot, anything other than pure text can come out looking like garbage.

    Anyways, thanks for an excellent, very helpful, article.

  4. Your blog was still slow when I accessed it. One thing you might consider is changing host. Also if your sql isn’t configured correctly can also cause slow load times. There are so many things that cause the problems it is hard to lay down any one single solution.

    I use a couple of these plugins myself and have the very useful for server load time and bandwidth usage.

  5. Hey Sam, my tips were aimed at wordpress not blogger and Icey is only for .css files, not html. cheers

  6. thanks Chris, I still sometimes see slow loading but generally it is ok, and as you pointed out I definitely need a new hosting service, I think I am stuck on their 486-100mhz server in their back shed ;-) … definitely a task for the new year !

  9. Thats a plugins (widgets) developer fault. Wordpress has various build-in methods/functions for managing external files (js/css)on specific case and task i.e: is_active_widget(id) || is_?(?) || get_option(’active_plugins’) ||add_action & add_filter ). Unfortunately not all used it thought. I found a good theme (suprise) that cleverly apply this methods. Its only load the external files if the widget or plugins is active on the request page. its even combine-hash-gzip all the external as single files (js/css). You can view it on my blog for demo and check how it hook openid & wordpress default widgets external files.

  13. well i just lost my comment since when you hit tab it doesn’t go to the submit button…

    so here is the shorter version.

    Thanks for the tips. I was unaware of the text widget issue.

    after compressing the css files we did that with the js files as well and then changed the .htaccess file to send gzip’d versions of those files if the browser supports it.

  14. I recently became aware of 2 problems that severely impact your WordPress blog performance and slows down your blog.

    NOTHING impacts it more then bloated database! The tables of your database “wp_options” can grow pretty large and bring your blog to a c-r-a-w-l.

    It forced me to look at bigger issue as in process of cleaning I discovered that all plugins I have ever installed and even a couple themes managed to leave entries in very same table contributing to the total size and slow load times.

    All the plugins and even some themes use wp_options to set its setting and as such contribute to the size of the table. It is very same table used by WordPress to store ALL settings related to your blog and every time you open any page it has to be read and processed.

    When you deactivate plugin or decide to switch theme (assuming it stored its settings in wp_options) – it NEVER cleans behind itself.

    You have to login to your phpMyAdmin and open database for your blog and Browse action for wp_options table and go through it record by record.

    It may take hours…but your blog speed and users will Thank you for it.

  15. Hmmm….I hit submit and went to the top of the page?

    My short version is… All the plugins and even some themes use wp_options to set its setting and as such contribute to the size of the table. It is very same table used by WordPress to store ALL settings related to your blog and every time you open any page it has to be read and processed.

    So….You’ll need to login to your phpMyAdmin and open database for your blog. Click on Browse action for wp_options table and go through it record by record.

    May take hours but your blog and users will Thank you for the increaed speed.

  16. I have tried to post a valuable comment twice…and I float back to the top of the page after clicking submit. Guess you don’t want anymore comments…but then you should close the comment box.

  32. I’m using Firebug to monitor the network page loads on my WP site. The multilevel navigation plugin seems to be my main culprit. When I hover over the timelines, the largest number seems to be next to “waiting for response” on each GET. My question is: Does this mean my server is slow or is it referring to something else? I know just enough about coding to be dangerous. Any help is appreciated.
