wire.lsp's recv-exact previously accumulated received chunks via
`(string-append acc chunk)` in a loop — quadratic on payload size.
Replaced with a chunk-list accumulator + single `(apply string-append
…)` at the end. Lumbda's string-append knows total length up front
& allocates once.
Python tier now scales linearly across input counts (~22 µs per input):
workload Python C tier
small (3 × 16 B) 1.25 ms 0.16 ms 8× C win
small (100 × 16 B) 3.39 ms 0.40 ms 8× C win
medium (1000) 23.52 ms 2.60 ms 9× C win
med (10k) 220.15 ms (cliff)
huge (50k) 1,100 ms (cliff)
huge (100k) 2,225 ms (cliff)
huge (1M) 23,811 ms (cliff)
C tier cliffs somewhere between 1k & 10k inputs per call — its reader
hits a payload limit we still need to track down. CUDA kernel for
1M × 16B finishes in ~47 ms on this 3090, so at huge sizes the wire
cost dominates regardless of tier.
Web page updated with the linear-scaling table & honest framing: at
small inputs C wins by 9×; at huge inputs the right next move is a
binary wire mode parallel to the daemon's already-binary portal
format. Stalls are gone.
