How to speed up the download speed

 Hi, 

Today, I have a Test. I download a 1G file from Google Drive. I found that the download speed is around 2xx-3xxkb/s. If I download the file w/o through the firewall, the speed will jump to 1M to 2M /s. 

I don't know this download speed 2xx-3xxkb/s is correct or it can be improved. 

Please Help!

Thanks!

**I haven't set any Qos.

  • you should reach almost the available bandwidth with firewall too.

    at the dashboard check current CPU and used bandwidth at the external interface.

    Try to upload a file ... which download speed do you get

    because i see 1/10 of availeble bandwith i think a duplex error is possible.

  • Following is the capture Screen

    ** Remark : ISP provided the internet speed is 1000M.

     

    Does the drop speed relate to the antivirus Scanning? If yes, how can I disable the antivirus Scanning?

  • All the information about speeding technology has been discussed here. This will definitely help all the users. Is this applicable for iOS? I am facing iTunes error 9. How can I fix it?

  • You have a 1000MBit (1GBit) NIC  speed or you should reach 1GBit up-/download speed?

    AV / IPS may reduce the throughput ... but not so much.


    one moment later ... OK, you wrote "If I download the file w/o through the firewall, the speed will jump to 1M to 2M /s. "

    So you can't use an 1GB Up-/Down-link

    But at your pictures i see 1-2,5 MBit interface load too ... the same as expected

     

    Try to download these file with and W/O Firewall:

    http://ftp.astaro.com/UTM/v9/up2date/u2d-sys-9.510005-600005.tgz.gpg

    which speed do you reach?

  • Yes, ISP provide 1G speed.

    When download a file , it will not use all resource. Otherwise the network system will lag.

    Today, I download the same file from DMZ. The speed is around 1 to 2M download speed.

    About the u2d-sys-9.510005-600005.tgz.gpg file testing, I will try on Monday(HONG KONG Time).

    Thanks!

    Hi Dirkkotte,

     I try 3 methods. They are through "firewall" , "DMZ" and "with out firewall". Both result are around 5M/s ~ 5.5M/s download speed.

  • ok, thats not much ...

    possible if the ftp server is located far from your country.

    But it is more than the reported speed (2xx-3xxkb/s) from first post.

    is it possible you try a local speed-test? With and W/O Firewall?

  • Hi Dirkkotte,

    Following is the speed test result from Government Web Site.

    The download speed drops so much when use the firewall.

  • that's OK. the proxy functionality often distorts these results in this way.
    with "normal" network traffic and multiple users, significantly more throughput should be achieved.
    but the values displayed here (> 300MB / s) are not really bad ... and far from 1-3 MB / s.
    so it is difficult to understand the problem.

    Do you use the chinese gov seceurity systems form HK too?

  • But the download speed drops around 60% when through firewall. It is still not reasonable.

    Does the problem come from the firmware?
