You were useing web file manager to transmit a big file via NFS?
I don't really understand your test topology, could I get more detail about it.
My tests are based on real file transfer speeds betwen two high end NAS form QNAP.
I tested, what effect has a LACP during real file transfer of big file (movie with 33,5 GB size).
I tested file transfer only between QNAP NAS models TS-509 or TS 809U-RP
File transfer protocols: nfs and ftp (copy only via web file manager or download manager diretly on NAS)
Gigabit switches on which I tested (all with IEEE 802.3ad support, I verified the LACP configuration on both sides switch-NAS)
- Netgear GS108T
- HP ProCurve 1800-24G
- HP ProCurve 1800-8G
Here are latest results:
QNAP TS809U-RP -> QNAP TS509 53,07 MB/s
) 52,67 MB/s
) 70,66 MB/s
) 72,29 MB/s
QNAP TS509 -> QNAP TS809U-RP 58,00 MB/s
) 67,59 MB/s
) 69,79 MB/s
) 70,37 MB/s
The LACP don´t increase file transfer speeds.
These speeds are limited other componets (CPU, Memory, Controller, HDD).
Working the LACP correct? (latest tests was done with firmware 2.1.5 on all NAS)
If the LACP working - in which situation can this feature increase file transfer speeds?
... maybe my thinking about LACP is wrong and this feature has another function ...
