Hi Alan, in my tests I found that using buffer transfer is pretty much immediate (0-2ms) whereas using copies goes up to ~30-40ms (for a 10MB data buffer) - not the end of the world, but big difference when using workers for in a realtime context (e.g. animation). In addition to your message object you only need to specify another array of which objects to transfer, the onmessage handler stays the same...
;; send (let [buf (.-buffer (js/Uint8Array. 1e7))] (.postMessage worker #js [buf] #js [buf])) Maybe important to point out: You can't transfer a typed array directly, only its underlying ArrayBuffer. After transfer the entire typed array will be unusable by the sender. Any writes to it will fail silently and reads will produce `undefined`... Hth!
