Hello,
I have a Leap 42.2 desktop with a Ralink RT2800 PCI 802.11n Wi-FI card. I have recently upgraded my broadband download speed to 40 Mbps
- On an Android phone and on a Windows 10 Toshiba laptop, about 35 MBps, which sounds about right for this Internet connection.
--- MBps, or Mbps? There is a difference...
- On the Leap desktop using Chrome or Firefox, about 12 Mbps!
---- Have you tried looking at the traffic with a network packet monitor like wireshark to see if both use the same type of protocol and packet sizes? On Windows, back in older versions of FF and TB, both were terrible for local network performance compared to other apps due to them both using a maximum TCP packet size of 4K. A few other apps use small packet sizes -- unless they are tuned to allow 100's to 1000's of packets outstanding before needing a packet acknowledgement, they will suffer a round-trip delay for every packet. For fast network IO, I use large packet sizes (1MB or larger), with peak speeds using 16-256MB/read or write (these are _wired_, 10Gb connections, BTW). I've seen ThunderBird take over 30 seconds to send a 5MB email, that had to send the file from win7 via SMTP to my linux-box and save a copy via IMAP to my 'sent' mail. Over the same net, I've seen speeds average a bit over 560MB/s (doing a tar of a Win7 directory mounted via CIFS on my linux-box. Hope that gives you some ideas on how important an apps settings can are for network throughput. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
