The document outlines benchmarking results for optimizing Magento 2 performance using different caching methods, specifically Redis and Varnish. It concludes that Varnish is the fastest option, while Redis does not significantly enhance performance when file caches fit in RAM. The document also emphasizes the ease of caching configuration in Magento 2 compared to its predecessor.

1. How to configure Magento 2
for max performance
(based on 1 benchmark :)
Daniel Genis

2. Difficulties when benchmarking
Not representative for every shop
Easy to make mistakes
Many choices:
1. various benchmarking methods
2. various ways of measuring
3. cold or hot caches
Complexity

3. The shop
Sample data magento 2.0
not that many products
no extensions
about 3000 unique frontend URLs
Benchmarking frontend only

4. The benchmark tools
JMeter test plan, 20 threads doing:
Request a frontend page + all static content
upon completion wait 2 seconds
Request a different frontend page + static content
Each thread has a pre-generated list of urls
Each thread makes 50 requests per default
A warming run was done before actual benchmark

5. The test server
Hypernode - Magento Grow
2 cpu cores
2 gb ram
SSD storage
Small test server
Easier to push to its limits
And to show off our Hypernode setup :)

6. no redis, no varnish: 378 ms median
ms
20 threads 50 req / thread

7. redis caching, no varnish: 372 ms median
20 threads 50 req / thread

8. Redis caching 10 threads: 263 ms!
10 threads 100 req / thread

9. varnish caching: 116 ms !! :)
20 threads 50 req / thread

10. Statistical summary
clean install redis cache redis 10thr varnish cache
Average 412 ms 403 ms 278 ms 125 ms
Median 378 ms 372 ms 263 ms 116 ms
95th
percentile
727 ms 710 ms 423 ms 187 ms
CPU util 100% 100% 50% 20%
Relative 324% 321% 226% 100%
Nice!

11. Conclusions
1. Varnish is obviously the fastest setup
2. Redis gives no measurable improvement
(when local file cache fits in RAM)
3. Magento 2 is awesome
4. Cold cache: Magento 2 is still Magento :)

12. Observations
Caching is easy to setup (compared to Mag1)
Varnish cache built-in
Redis cache built-in
No plugins needed
These benchmarks were very bandwidth sensitive
Static content!
html: ~10kb
total incl static: ~1mb

13. Bonus: disk cache vs Redis cache
Cache entries are stored in 'core_cache_tag' table
On multistore environment this table can grow very large
SELECTS are fine
but UPDATE/INSERTS become more work (scalability issue)
Redis is more efficient (than memcached or default cache)
For various query/update scenarios
Has high availability (i.e. master/slave replication)
