Developer cuts APIFOX plugin sync time 64% with Codex

On October 31, 2026, a V2EX user posted that they had used Codex to rework the sync plugin they rely on in APIFOX, and shared what was changed and how much time it saved.

According to the post, Codex found that a fixed wait of sleep(100ms) ran after each class finished processing. The user did not state a definite reason for it, and guessed it was meant to free up resources for the compiler. Three changes were made: the per-class fixed wait was cut from sleep(100ms) to sleep(1ms); unnecessary debug logging was reduced; and the upload payload was switched from indented, newline-separated JSON to compact JSON, shrinking the string size and the amount of data transferred.

The benchmark covered 2,960 classes, 162 Controllers, and 210 return-type inferences. Class scanning and parsing dropped from 245.0s in the original version to 90.0s and 72.0s across the two modified runs. Post-parse processing and upload dropped from 31.8s to 16.7s and 27.5s. The complete task fell from 277.2s to 107.4s and 100.3s. Taken against the latest run, the total time saved came to 176.9s, or roughly 63.8%, which is the figure behind the roughly 64% improvement in the title.

The post closes by suggesting that anyone hitting a similar slowdown can apply these changes directly with an Agent tool and then verify the effect in a fresh workspace. As of the report there was no further information on whether the plugin's author or APIFOX had reviewed or adopted the changes.
