Slow FTP Speeds

Hi All,

I'd like to pick your brains a little on an issue that is quite confusing to me.

I have a dual boot system with Arch and Windows 8.

I haven't booted Windows in months, but I was downloading off an FTP today in Arch at about 300K a sec, thinking to myself that this is quite slow considering I have a 100Mbit connection downloading off a 10Gbit server.

At first I thought it may be Filezilla, so I tried a few other FTP applications and got the exact same performance.

At this point I'm wondering if the site I'm using is slow, maybe my node is saturated or there is a problem with my modem. I figure I'll boot into Windows and see if it was OS specific first. I start up filezilla in Win 8, connect to the same site, resume the same download. BAM 10MB a sec!

What the hell is going on here? Why would my network performance in Arch be so woefully crippled compared to Windows?

Any suggestions would be great!

Thanks,

ewaller

Re: Slow FTP Speeds

Well, it might be nice if you told us whether it is wired or wireless.
Which chipset your NIC is using.
If it is wireless, are you using g,n,ac ?  How about windows?
Are you using a router?
Does the router provide the same IP address to windows as to Linux?  Is QoS set up in the router?
What is the output of ip addr   ?
of ip route  ?
Did you set your hostname correctly? Did you configure /etc/hosts?

Re: Slow FTP Speeds

You're right, I should have provided more info.

NIC: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 01)

Both OS's are using a wired connection

I use a router/modem combo from my ISP. It's a Hitron CGNM-2250 Advanced WiFi Modem. There is no QOS setup.

Both Arch and Windows obtain the same IP from the router.

ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:24:8c:69:ed:7a brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.13/24 brd 192.168.0.255 scope global enp2s0

    inet6 fe80::daa5:467a:5701:995a/64 scope link 
       valid_lft forever preferred_lft forever

ip route

default via 192.168.0.1 dev enp2s0  metric 202 
192.168.0.0/24 dev enp2s0  proto kernel  scope link  src 192.168.0.13  metric 202

/etc/hosts

127.0.0.1	darkwing.localdomain	darkwing localhost
::1		localhost.localdomain	localhost

Hostname is also 'darkwing'

Re: Slow FTP Speeds

UPDATE:

I did some more research and found an option in my BIOS. "LAN BOOT ROM"

I've enabled that and have gone from 300Kb/s to 1.4MiB/s. A stark improvement, yet still not what it's capable of!
