Parser
- Optimize
parseInteger - Use mmap
- Consider
madvise(MADV_DONTNEED)not to page-in whole .wasm contents
- Consider
Translator
- Reuse internal Array buffers across translation to avoid allocation a fresh Arrays for each translation
removeAll(keepingCapacity: true)

Research direction
Start with the attached launch trace and locate the parser's parseInteger path, the mmap-related loading code, and the translator's internal Array allocations. Compare parsing and translation time and memory behavior before and after reusing buffers with removeAll(keepingCapacity: true); done means measurable improvement without changing translation results.
