Duo Performance and lockout
Hi All, I've been reading up a lot on performance issues that people are having but none seem to quite match mine. I apologise if I've writing about stuff already covered, but the performance troub...
(a) duo v1 running 4.1.13
Yes but not sure how to get if it's v1
(b) xraid (raid 1) disks on the HCL
xraid yes, not sure which version. WD green caviar disks. HCL?
(c) only squeezebox and transmission installed
and ssh and noled, although I've removed noled now.
(d) jumbo frames disabled, normal MTU of 1500
Yes
(e) normal redundant volume status reported in frontview.
Yes
(f) plenty of space on the OS partition
Yes
(g) no SMART errors reported
actually quite a few errors (see below)
(h) modest TCP retransmissions reported
high when using transmission, otherwise pretty low
(i) intermittent very slow transfer speeds in both directions under many circumstances
1. direct connection or through GS108 switch
yes
2. 1 gbit or 100 mbit configuration
yes
3. with 3 different win7 machines and two media players
also xbox360, a sky+ box, panasonic bluray but none connect to nas
(j) turning off transmission does not help
correct
(k) top does not show high CPU activity during slow network connection
correct although not sure my timing is quite right
(l) nothing seen in the logs
actually lots in the logs but hard to know what is important and what is just noise.
(m) a full backup has been created
Yes, and I agree, maybe a full reset is the next step :)
