Slow Server

[0plus1]

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?

Please post the output of the command:

Are there any errors in Apache's error log?

That fixed the error, but the extreme slowness still remains.. what should i do?

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.

Done, thank you again for your help!

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:


server1:~# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 260 MB in 3.02 seconds = 86.19 MB/sec

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:

server1:/dev# hdparm -Tt /dev/sdb

/dev/sdb:
Timing cached reads: 2220 MB in 2.00 seconds = 1109.92 MB/sec
Timing buffered disk reads: 260 MB in 3.01 seconds = 86.30 MB/sec

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...
