Hi all, In my test with fuse-2.7.4, I noticed that a fuse_write request is at most 4KB. So a user write of 1MB is translated into multiple fuse_write each of which is 4KB. is there a tunable that determines the size of a fuse-write? Or, how can I change fuse module to increase this size? Also, I noticed that each fuse_read() is at least 4KB, at most 128KB, with 128KB read-ahead if possible. Can I change the size of a fuse_read? In my application I want the size to be bigger. Thanks! -Neutron |

You need fuse 2.8 and -o big_writes. > Also, I noticed that each fuse_read() is at least 4KB, at most 128KB, > with 128KB read-ahead if possible. > Can I change the size of a fuse_read?

As far as I know, that's not yet possible. -Nikolaus -- »Time flies like an arrow, fruit flies like a Banana.« PGP fingerprint: 5B93 61F8 4EA2 E279 ABF6 02CF A9AD B7F8 AE4E 425C |
