v0.3.1
v0.3.1
This version is mostly performance improvements & refactoring of current codebase.
Features
- Panko::JsonValue - wrapper for json values to use Panko::Response
Performance Improvements
- Caching types in attributes - Instead of re-fetching the type of attribute every time, we cache it and invalid it based on the record class being serializer.
- Moving attributes & associations to be backend behind C structs - and saving the name of attribute/association string and symbol to avoid necessary conversions
- Type Casting of JSON - is now done using Oj instead of relying on AR type to do the deserialization
- Caching serializer between runs - In method attributes, we create serializer instance, now between runs we cache it so we don't need to re-create.
We can't talk about performance improvements without showing some numbers!
Real-world benchmark:
I used the infrastructure in work and popular endpoint that serializes 7,884 entries,
here is are different between v0.2.2 and this version -
| Metric | v0.2.2 | v0.3.1 |
|---|---|---|
| Avg Response Time | 2.10s | 1.46s |
| Max Response Time | 2.40s | 1.90s |
| 99th Response Time | 2.35s | 1.67s |
| Requests Per Second | 0.47 | 0.68 |
| Total Requests | 142 | 205 |
the tests were done on different environment for testing only with wrk - 5 minute
Thanks to Bringg (my employer) for providing the infrastructure & data for those benchmarks.
