This is probabely the reason for you bad performance. My choice would be normal (=async) NFS mount plus DRBD in protocol C. This has the same semantics as a local filesystem: The return of the write system call means that the data is in the OS's buffers, the return of the fsync()/fdatasync() syscall means that it is on disk.
