Hi,
Can anyone please help me to solve a puzzle I have discovered,
when testing my 209+ ?
I have a 209+ with a single 1.5TB Seagate drive connected to a
Netgear GS108T (with JF enabled), which in turn is connected to a
laptop with a PCIe gigabit NIC.
During upload testing to the NAS, without Jumbo Frames, enabled I measure a
consistent 28MB/s. The excellent reviews here (minor brown nosing, but never the less true) indicated there may be some more horsepower to be had by such a setup so I have experimented with JF.
To begin with I set both NAS and laptop to 4K, tested with the ping options
to ensure the packets are not begin segmented and then ran tests.
The upload performance went from 28MB/s to 3MB/s.
And any combination of JF sizes sees no change in upload speed.
It's about 10 times slower. However as soon as I switch Jumbo Frames off
on the Synology NAS performance returns to about 28MB/s.
Am I failing to set something up correctly? Or is there any check list I can reference to see where the bottleneck is forming ??
Any help gratefully received.
