3. Performance testing - for what?
●
●
●
●
●
Find a problem previously
Evaluation of site possibilities
Evaluation of implemented optimizations
Regression testing
Report to client

4. Tools
●
●
●
●
Online services
Desktop apps
Console utilities
Php

5. Tools
Jmeter - why we use it?
● Flexible
● Free
● A lot of inbuilt and additional modules and
plugins

6. Criterias and methods
Criterias:
● Response time
● Throughput
● Hits per second

7. Criterias and methods
Test strategy:
1. Testcases - user behaviour emulation
2. Stand preparation
3. Load
4. Results analyze

8. Example
Initial data:
1. Project A before optimization:
● no memcache
● Varnish doesn’t cache anything
● no ESI
1. Project A after optimization
● Enabled memcache
● Enabled ESI
● Varnish is configured
● Cache per roles

9. Example
Response time - “before”

10. Example
Response time - “after”

11. Example
Results - response time
Average value “before”: 9000ms
Average value “after”: 330ms

12. Example
Throughput - “before”

13. Example
Throughput - “after”

14. Example
Results - Throughput
Average value “before”: 6.2 transaction/sec
Average value “after”: 114 transaction/sec

15. Example
Hits per second - “before”

16. Example
Hits per second - “after”

17. Example
Results - Hits per second
Average value “before”: 4 hits/sec
Average value “after”: 100 hits/sec

18. Conclusion
What can we cache?
●
●
●
●
●
●
code (APC)

cache_field
cache_filter - filtered data
cache_form - no affect on performance
cache_image
cache_menu - all menu links and parametres
cache_page - global cache for anonymous only
cache_path
