There has been many reactions to the 2.2.9 FW. Many experience very slow transfer speed. I came from 2.1.92 and had the opposite experience, getting almost 100% better.
However, I’ve been grokking a bit. First I looked at the Samba Configuration and did some changes:
[global] socket options = TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT SO_KEEPALIVE read raw = yes write raw = yes
(smb.conf contains much more, of course)
socket options = TCP_NODELAY SO_RCVBUF=65536 SO_SNDBUF=65536
My tests indicate +1MB/s on read, +0.5MB/s on write with the altered /etc/samba/smb.conf. For me that is 10MB/s when reading from SS, and 8,5MB/s when writing.
I notice smbd (Samba) uses almost all CPU and 2/3 of memory. Anyway - the performance is not good. I believe WD should carefully consider how to tweak Samba. I’m sure other tweaks and tunings are possible.
Anyway - I tried FTP and got very different results:
Download: 13.5 MB/s
Upload: 17.5 MB/s (yes, writing actually much faster than reading!)
So at least - when reading or writing in bulk, use FTP.
And actually, mapping an FTP site directly into Explorer is easy in Windows. I found an easy howto here:
