[Gluster-users] Does Gluster not support mul-thread to the same file?
I used a mul-thread program to write the same file in gluster. We just gained about 30MB/s write performance by gluster native client, whereas, using the same program, it's 100MB/s writing performance if mount gluster volume by NFS. Could anyone tell me why? and how to improve write performance for mul-thread writing to the same file mouted by gluster native client. Thanks.

How does multithreaded writes behave with NFS client and Linux kernel NFS server? Avati -------------- next part -------------- An HTML attachment was scrubbed...
