scovich opened a new issue, #7869: URL: https://github.com/apache/arrow-rs/issues/7869
I added several timestamp markers (`std::time::Instant::elapsed`) to the `test_json_to_variant_object_very_large` test and ran with `cargo test --release`: |elapsed time (ms)|delta (ms) | finished step| |-:|-:|-| 5 | 5 |generate data structures and json string 250 | 245 | `json_to_variant` 593 | 343 | `Variant::try_new` 1758 | 1165 | `variant_to_json_string` 1839 | 81 | build variant directly 2171 | 332 | `Variant::try_new` 2758 | 587 | `JsonToVariantTest::run` ``` We can build up the raw data structures _and_ directly create a JSON string from them in 5ms, and parse the JSON string to a variant value in ~250ms, but it somehow takes 1.1 _seconds_ to convert the resulting variant back to a string. Something seems wrong here. `Variant::try_new` also seems quite slow (330-340 ms). -- This is an automated message from the Apache Git Service.
