[RFC][QUESTION] fuse: how to enlarge the max pages per request

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Miklos,

>From my test, a fuse write req can only contain 128KB which seems
limited by FUSE_DEFAULT_MAX_PAGES_PER_REQ in kernel. I wonder if I
could enlarge this macro to get more bandwidth, or some other adaption
should be done?

Up to now, many userspace filesystem is designed for big data which
needs big bandwidth, such as 2MB or more. So could we add a feature to
let the user config the max pages per request? Looking forward for your
reply.

Thanks,
Jun
