Performance Advocate at Dynatrace

15. PERFORMANCE THREATENS GOALS
In November 2014 we had a problem.
We discovered that our Magento Shop was
actually pretty slow!
So what do you do in that situation?
→ Our infrastructure was very limited at that
time, so let’s change that (WRONG!)
→ Don’t we know someone who works at that
performance company?
→ It turns out that in fact we had problems with
our code and with Magento!

16. PERFORMANCE THREATENS GOALS
Within the first session with Harald we discovered the first
major problems:
→ lessc CSS pre-processor
→ Social Login Module
→ PHP execution was really slow

17. less CSS preprocessor
PHP execution presented
a major global bottleneck
for our page load times!

18. less CSS preprocessor

19. less CSS preprocessor

20. Social Login Module
server-side calls to
external services
we did not use

21. Slow PHP execution
average contribution of
PHP compilation time
for fast requests!

22. After updating to PHP 5.5
PHP compilation time could
be reduced considerably just
by using PHP 5.5 + Opcache!

23. PERFORMANCE THREATENS GOALS
One directly business-relevant issue:
A seemingly harmless layout change
slowed down our page considerably!
What had happened?
We had added a small information to our
product listings: the available stock quantity
of each item in the list
Analysis: drill-down of using Dynatrace and
sensors to measure method-level performance
Problem: the PHP method to calculate the stock
quantity was extremely inefficient
Solution: pre-calculation of stock quantity values
and caching of those in the database + caching
of database results in private member variables
Consequences for our workflow?

24. STATUS QUO
Our infrastructure changed a lot since the
beginning.
We are thoroughly monitoring every change
that goes live and included performance
monitoring in our development & review
process.
Our website evolved over time, but we see a
clear correlation between our website
performance and our conversion rate.
