This number is currently fixed to 2. If an FFI consumer requests a PoSt over more than 2 CommRs, we pair up CommRs and sequentially generate a PoSt for each pair.\n\nPoSt generation should take approximately one proving period to complete. If we need to generate more than one PoSt in a proving period (because we have committed, say, 10 sectors) and we generate those PoSts sequentially... well, we aren't going to finish by the end of the proving period.\n\nThe [spec](https://github.com/filecoin-project/specs/blob/master/actors.md#commitsector) shows that we should use [262144](https://github.com/filecoin-project/specs/blob/master/proofs.md#filecoin-proofs) for `POST_SECTORS_COUNT`.\n\n### Acceptance criteria\n\n1. FFI `generate_post` signature does not change\n1. We generate a PoSt for 262144 CommRs in a single shot\n1. Produce an error if FFI `generate_post` called with more than 16384 CommRs"}}
