Do it at build time
A metatable keeps field names in the running script. TypeScript can check them at build time and emit plain positions instead. For 100 buffer records, that's of the script's memory rather than , with reads about 12 times as fast.

What does named access cost?
A shared metatable lets code read arrays and buffers by field name. In the test, 100 records use about of the script's memory with named fields, or as buffers with names.

Capacity··10 min
Size lists before they round up
An appended 285-entry list in SLua uses 384 slots at 16 bytes each. I test when table.create saves memory and how to size my HUD's paint lists.

Data··9 min
Pack records before they fill linkset data
For this 14-field test record, linkset data holds about 660 JSON objects or 6,000 packed buffers. Compare storage savings with script memory and code costs.
