[Issue] ProFTPD & Apache are slow

Yeah, it looks like it skipped a couple of packets in that output.

So you may indeed be seeing a network problem of some sort. If you send 50 packets to your server, you should be able to rely on the fact that all will be returned. If that doesn’t happen, something between your desktop and your server is wrong.

This is where it gets tough – it could be anything :slight_smile:

It could be a network card, network cable, router, switch, hub, and so on.

You can use tools such as traceroute to help you diagnose the issue – it can help you figure out roughly where the problem is occurring. I like the program “mtr” for these sorts of issues, though it’s only available for Linux.

I will supply some more pings during this day and contact my datacenter in order to check the hardware since this is going on for month’s already. And they did checked it a couple of times so far…

I am on IRC also by the way under the name “Companion”

It doesn’t look like you are always getting packet loss. It shows up in some cases, and not others. If you only ever see it when doing the ping from your desktop, that may mean it’s something with your desktop machine, or perhaps your home ISP.

Or, it could just mean the problem is intermittent :slight_smile:

But, the above output definitely shows a problem.

Ran MTR a couple of times and these are the results:

It happened on multiple ISP’s.
Have this issue from:
KPN, Ziggo, directadsl, XS4All and UPC

When you run mtr, you don’t necessarily want to use a “-c 1” – that’s not quite enough data. You’ll want to let it sit for awhile. If you allow it to run for a bit, are you seeing packet loss when going to the sites you tried above?

If your issue happened at multiple data centers, then your issue is likely either with your server or your desktop (or desktop ISP) :slight_smile:

One thing you might try is to run:

ifconfig eth0

With that, do you see any RX or TX errors?

It has always been at the same datacenter (this server), this stuff hapened when we re-installed the server cause of a corrupted kernel. Further its pure server side cause switches have been reset and rebooted from my knowledge. Users can only access the websites with are slowly loading. The ISP’s I named were from the home users.

The sites that are currently run are:

CSS loads rapid but images are still a pain :frowning:

Will forward this topic to the datacenter*
