Hi, everyone, I met a problem of improving the fuse write performance in the kernel of 2.6.18, I know fuse 2.8 has support big write well in the kernel >= 2.6.26, Howerver, the write granularity is still 4KB in 2.6.18, If you have solved the same problem before, would you please tell me the method or some information? Here is the configuration of my system: OS CentOS 5.5 kernel 2.6.18 fuse kernel module:2.7.6 fuse lib 2.8.2 Thank you very much. any information would be pleased. Jing 2010.12.13 |

Thank you very much for your reply. As user application is combinded with the kernel of 2.6.18, it's impossible for us to change the kernel. May be I have to choose the difficult way. Is it easy to change normal write to async write? If so, I can integrate mulitple 4K write requests at the fuse client component and send big write to my servers. However, I check that fuse kernel model for kernel <2.6.19 dosen't support aio, I still have a lot of work to do. Best wishes.
