    I installed ISPConfig correctly, everything works exept that php script takes a load of time to work, for example: www.twinpics.eu/info.php looks like it progressively loads. I use an externall DNS. Do you have any tips?

    Are there any errors in Apache's error log?

    Is the server in a data center, or do you host it yourself (e.g. at home)?

    I' m hosting it myself using a public ip on an HDSL. The problem i found is that while the downloads are pretty fast (wget ispconfig steady 400 kbs) the upload is painfully slow. I tried to download from ftp a big file (an sql dump) and it downloaded it at 0,2kbs. Now i'm thinking is a connection issue but:

    may it be a problem on the server?
    i'm using the ethernet card of the mobo with an external .ko file.

    How fast/slow is the server when you connect to it using its private IP address?

    Short Answer: it's the same..

    I tried: ftp directly with ip (0,9 kbs); ISPConfig admin page with ip (feels the same: slow).

    I suggest that you install munin. With the help of the graphs it might be easier to find out what's the reason.

    Everything's looking fine. All that I can think of is a slow hard drive. You could try to speed it up with hdparm.

    I tried a quick test /w hdparm:


    Code:
    server1:~# hdparm -t /dev/sda
    
    /dev/sda:
     Timing buffered disk reads:  260 MB in  3.02 seconds =  86.19 MB/sec
    Code:
    server1:~# hdparm -T /dev/sda
    
    /dev/sda:
     Timing cached reads:   2200 MB in  2.00 seconds = 1099.51 MB/sec
    Seems ok to me?

    Couldn't be instead a problem of the internet provider? Or a problem of the router? It seems very strange this behaviour to me.


    EDIT: sdb seems pretty off:

    Code:
    server1:/dev# hdparm -Tt /dev/sdb
    
    /dev/sdb:
     Timing cached reads:   2220 MB in  2.00 seconds = 1109.92 MB/sec
     [B]Timing buffered disk reads:  260 MB in  3.01 seconds =  86.30 MB/sec[/B]
    I do think I'm using sda only though.. how come?

    Seems to be ok. I have no idea why your server is so slow. :(

    In your opinion, could it be a problem of the NIC? Could it be a problem of the internet provider? Do you think that formatting everything would resolve something?

    It could be anything, but I'm not sure what it is...
