deflate.c:603: is a duplicate of #207, #208, #261, #288, #327 and already resolved in the develop branch by 38e8ce3.

Since this is in the contrib stuff: I tried to contact @gvollant few years ago, but got no replies.

Finally resolved by 0884b80a7ee5783b6193d7e2c58f997d121d3245.

@emmenlau FYI I updated https://github.com/tbeu/matioPerformance to the upcoming libmatio v1.5.24. [test_suites.zip](https://github.com/tbeu/matio/files/5284857/test_suites.zip) from https://github.com/tbeu/matio/issues/157#issue-709222187 still is a performance bottle-neck.

Fixed by [274dfef](https://github.com/tbeu/matio/commit/274dfefceb43b60dbcfb1e4f2606d26c73214a0e).

Can you please give [f058e5d](https://github.com/tbeu/matio/commit/f058e5dfbaa8bc49fbe76631b6dbf7637be04b10) a try?

Thanks for confirmation!

Addressed by https://github.com/tbeu/matio/commit/0adfda6e129c2cedcae89a95918792e62fcd9bbd.

Thanks for bringing this topic up. I evaluated the code of `Mat_H5GetChunkSize` and also compared it with the auto-chunk feature of [h5py](https://github.com/h5py/h5py/blob/6b5af4c6495bf865fee5f036122187c21fcb17d4/h5py/_hl/filters.py#L335-L390). I see that `Mat_H5GetChunkSize` always sets the chunk...

@allwaysFindFood Any feedback would be appreciated.
