Will this kill the page cache?

[marsupialtail]

I see that this library is not using DirectIO to flush out the weights to disk:

this->fd = open(filename.c_str(), O_RDWR | O_CREAT, S_IRUSR | S_IWUSR);

Will this kill the page cache if you have a lot of weights?

Yes. We will add a flag to control it in the next release.
