[ask]your hdd speed

how fast your hdd that connected to asus router, when you copy file using samba(stop transmission/any torrent client/download first).


mine:
asus wl500-w
hdd seagate 80GB
speed 2MB/s at max

3,5 MBps

asus wl-500g premium v1
samsung f1 1 TB via unitek usb -> sata

Asus WL-500W overclocked to 300mhz (official clock speed of broadcom)
WD MyBook 1TB - read: up to 5mb/s ______ write: max 4.5mb/s
WD Essentials 500GB - all around 4mb/s

All measured via samba 2 on vista ultimate 64bit:cool:

Shouldn't be described a common approach to provide these figures?

wl500gP v1 (factory clocking = 264MHz)


[abcd@wxyz]$ hdparm -tT /dev/discs/disc1/part6

/dev/discs/disc1/part6:
Timing cached reads: 88 MB in 2.03 seconds = 43.35 MB/sec
Timing buffered disk reads: 32 MB in 3.12 seconds = 10.26 MB/sec

approximate rate 3.5MB/s read
approximate rate 3MB/s write

PX1270E-1G16 Toshiba 160GB 2.5" wl-500gP

is overclocking have impact to read or write speed of the hdd?

my hdd if connected to pc(directly) i can have around 21MB for read speed.

Yeah, because your pc has a gigaherz most likely or more... and a proper usb chip.

The point is that the cpu can never communicate optimal with the usb chip in the router due to the low clock and limited performance... so you get low speeds

I have a wl500gp v2 and the transfer speed in download is about 2.5MB/s and in upload of 3MB/s.
I tried to give an higher priority to samba processes and to stop all the unecessary processes but there weren't no changes.
During file transfer, the samba process uses about 70% of cpu.
I tried to overclock the cpu speed up to 275Mhz through the nvram set clkfreq command but i think that it doesn't work with the v2. After reboot "nvram get clkfreq" gives me a frequency of 275mhz, whereas "cat /proc/cpuinfo" gives me 239Mhz.

My next step is to try with a shielded cat5e cable then ... i must surrender :)

Good luck,
Brembs

cpuinfo doesn't include clock speeds...
so your router is clocked at 275MHz when nvram get clkfreq replies so...
