Download speed reduced after upgrading to 13.1.1

Hello guys,

 

I've upgraded our BIG-IP 2000s from version 12.1.3 to version 13.1.1 and after the upgrade, the download speed from our FTP server degraded from 3-4 Mbit/s to 120Kbit/s. I reverted the upgrade and the download speed went back to 3-4Mbit/s. I reinstalled version 13.1.1 again and again the download speed went down to 120 Kbit/s.

 

Nothing else changed, only did the upgrade. Also tried different TCP profiles after the upgrade but it didn't change anything.

 

Thank you Daniel

 

btw: I wanted to open a service request but it keeps saying "This serial number is unavailable for use"...

  • Hi Daniel,

     

    First of contact F5 about your your problem "This serial number is unavailable for use":

     

    send an email at SupportOne@ and ask them why you can not open a ticket with your serial Number.

     

    I think that you don't have right to open a ticket your email and this serial number. Ask to SupportOne@ to allow you to open a ticket with this serial. I do it regularly for my clients and it takes no more than a day.

     

    Second point, did you try to disable nagle algo in TCP profile?

     

    regards,
