So many figures to paste here…

Akamai & Forrester : 5 seconds to load, 20% of people bailing out
Shopzilla raised its revenues of ~10% by stepping down from 7s to 2s loadtime
Yahoo : +400 ms, 5 to 9% traffic loss and Google : +500 ms, -20% traffic
Amazon : +100 ms, -1% sales
Interrogated users claims that 2 seconds is fair, 4s is too much
52% of visitors consider speed an essential criteria for returning to a site
In 2010, 75% of visitors won’t come back if the site is slow (64% in 2006)
Speed directly influence your SEO & SEM efficiency
60% of visitors go away if a page load in more than 6 seconds on vid.stream…

►Google is also using speed as an important ranking factor (it’s official)
► Graph (given by Google) show clearly the target: 1.5s
► More and you are part of the red team called « SLOW »
► This is not good for your SEO ranking and SEM efficiency
► Relevance is still more important but… Don’t you have competitors ?

Large features panel & flexibility comes at a price
► Do it in assembler, it will be fast and you’ll become crazy
► The use of OOP language & framework help to work faster
► PHP is still an interpreted language (Vs Compiled one)
► Magento is a kind of “meta” framework
► The EAV model gave a lot of flexibility to the catalog but is costly
►

9
► APDEX is the key to “user oriented” benchmarks
► When you reach a 0,85 APDEX index, your server is
loaded but responsive, it’s a fair “deal”
► 4 levels for user experience (like your girlfriend, except
for the timings) :
o
o
o
o
Satisfied (for exemple less than a second)
Tolerating (from 1 second to 4 seconds)
Frustrated (more than 4 seconds)
Inacceptable (not served/errors)

Funkload is “Apdex aware”
It provide reliable tests and cute reporting capabilities
Allow you to draft scenarii and inject them
Will determine number of C.U (Concurrent User) with a fix Apdex
11
Yslow & Pagespeed are Firefox extensions to check your optims
► www.gtmetrix.com does it directly through a site (thus 4 all browsers)
► Reaching more than 90% is not easy, a default demostore, on a default
serveur (no optim) scores C/C (76/72%) and takes ~3,1s to load.
►
Those two performance rule set are among the most complete
► Respecting all rules will grant you a serious SEO & perfs boost
►
12
Less than 0,9 seconds to (fully) load the homepage
► 45 ms to get the home and start downloading the static files
► Grade A/A on Yslow & Pagespeed
► Deliver massive parallelizing and caching capability
► Serving up to 200 simultaneous actions (~50 000 Uniq visitor / day)
per front web servers with a Community Edition
► Serving up to 300 simultaneous actions on a Enterprise Edition (FPC)

Leave some 404
► Forget to activate Bloc Caching
► Badly coded Crons
► “Cold cache” effect
► Load a lot of products/categories on the Home
► Let the Log database be overcrowded
► Foreign includes
► Misconfiguring Magento’s cache setting
► Conception errors (like real time sliders)
► Hard disk access, nothing worse
