You can become a serverless blackbelt. Enrol to my 4-week online workshop Production-Ready Serverless and gain hands-on experience building something from scratch using serverless technologies. At the end of the workshop, you should have a broader view of the challenges you will face as your serverless architecture matures and expands. You should also have a firm grasp on when serverless is a good fit for your system as well as common pitfalls you need to avoid. Sign up now and get 15% discount with the code yanprs15!
Note: Don’t forget to check out Benchmarks page to see the latest round up of binary and JSON serializers.
Following on from my previous test, I have now included JsonFx and as well as the Json.Net BSON serializer in the mix to see how they match up.
The results (in milliseconds) as well as the average payload size (for each of the 100K objects serialized) are as follows.
Graphically this is how they look:
I have included protobuf-net in this test to provide more meaningful comparison for Json.Net BSON serializer since it generates a binary payload and as such has a different use case to the other JSON serializers.
In general, I consider JSON to be appropriate when the serialized data needs to be human readable, a binary payload on the other hand, is more appropriate for communication between applications/services.
You can see from the results above that the Json.Net BSON serializer actually generates a bigger payload than its JSON counterpart. This is because the simple POCO being serialized contains an array of 10 integers in the range of 1 to 100. When the integer ‘1’ is serialized as JSON, it’ll take 1 byte to represent as one character, but an integer will always take 4 bytes to represent as binary!
In comparison, the protocol buffer format uses varint encoding so that smaller numbers take a smaller number of bytes to represent, and it is not self-describing (the property names are not part of the payload) so it’s able to generate a much much smaller payload compared to JSON and BSON.
Lastly, whilst the Json.Net BSON serializer offers a slightly faster deserialization time compared to the Json.Net JSON serializer, it does however, have a much slower serialization speed.
Benchmarks do not tell the whole story, and the numbers will naturally vary depending on a number of factors such as the type of data being tested on. In the real world, you will also need to take into account how you’re likely to interact with the data, e.g. if you know you’ll be deserializing data a lot more often than serializing them then deserialization speed will of course become less important than serialization speed!
In the case of BSON and integers, whilst it’s less efficient (than JSON) when serializing small numbers, it’s more efficient when the numbers are bigger than 4 digits.
Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Skill up your serverless game with this hands-on workshop.
My 4-week Production-Ready Serverless online workshop is back!
This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.
We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.
If you enrol now you can also get 15% OFF with the promo code “yanprs15”.
Check out my new podcast Real-World Serverless where I talk with engineers who are building amazing things with serverless technologies and discuss the real-world use cases and challenges they face. If you’re interested in what people are actually doing with serverless and what it’s really like to be working with serverless day-to-day, then this is the podcast for you.
