Speed too slow when writing mat73 #85
Description
Dear all,
I successfully wrote my data to .mat v7.3, but I noticed the speed was extremely slow. To compare, the same data cost me less than 1sec to write a v5 .mat, but about 47sec for a v73.
Is this as expected? Has anyone faced the same problem with me? Any ideas to solve this?
I will keep trying to find out why and the solution of it.
Best,
Zheng

Indeed the time seems quite a lot, but if there is an issue, it may be more in matio https://github.com/tbeu/matio I guess, as matio-cpp only provides a C++ interface for the C functionalities provided in matio.
Anyhow, before opening an issue there, I think it make sense:

I opened an issue in matio.

I think that the mre should use matio, not matio-cpp, otherwise the mantainer does not know if the problem is in matio or matio-cpp. Furthermore, I would wait for having a working mre before opening an issue.

Hi @zhengliuer, did you happen to find the source of your issue?
zhengliuX commentedon Nov 26, 2024
Sorry, no. I was occupied by some other things, so I closed the issue for now. Now I have some time for this. And luckily, according to the test result from tbeu/matio#261 (comment), the performance degradation is confirmed.
