Hey, I totally get the need for speed but not at the cost of a corrupted model. For BIM, stick to pure lossless codecs—zstd or Brotli at a moderate level (around 10–15) gives you a solid 60–80% squeeze without blowing up the CPU. Wrap the compressed archive in a simple checksum (sha‑256 is my go‑to) and use a small manifest that tracks each chunk’s hash. That way you can verify integrity on the fly and roll back if a packet gets garbled. If bandwidth is really tight, split the file into 5‑10 MB blocks, compress each block separately, and re‑assemble on the client; this keeps the hash checks lightweight and lets you skip bad blocks without discarding the whole dataset. Just remember, never rely on a GUI tool—open‑source CLI tools like 7z or zstd are far more predictable and scriptable for a clean pipeline.
