Hi, I don't know if my question is LEAF especific or some broader
configuration issue. I don't have to much experience in this field, so I'm
probably asking nonsense. If I really should RTFM, please also tell which
one, I probably don't know which one also... :)
Well, here it goes: Up to some time ago everything worked optimally (two or
three months ago). At that time my ISP installed QOS in my node. They are a
little local wireless ISP. I've probably been one of the first subscribers,
so I guess the are up to some point learning while the build the
infraestructure. I have a 256 kbits simmetric? connection, and even if it is
wireless they give me an ethernet cable to connect to. I'm using LEAF
Bering-uLibc 2.3 as my firewall/router.
The problem is this: After they got the QOS running as they wanted, I started
to have some serious performance problems. All the Linux machines in my local
network had it's download speed cut by half, and the Windows machines by a
30%. All the time and downloading anything from any source. I called them
but, after some time, they told me that everything was OK, and that no one
besides me was (is) having such problems, so that I probably had my router or
PCs misconfigured.
I did nothing for some time because I had absolutelly no idea what to do or
where to look, but yesterday I noticed this: I was downloading a huge file
from a Windows machine and the speed was topping at 22 kbytes/sec, as usual
lately. That particular machine has also a Kerio personal firewall
installed, ...and the firewall was reporting that the raw download speed was
~32 kbytes!!!, not 22 kbytes as the Downloads windows of Firefox showed.
So I assume the effective transported payload was 22 kbytes/sec, but the raw
traffic as 32 kbytes/sec. This is a lot of waste to me... isn't it?
So, finally, the questions are:
- I didn't touch anything is the LEAF box, but I'm not getting the same
performace as before the QOS thing. Could it be that they (my ISP) have
something wrong? What should ask them for?
- Could it be that only now surfaced a misconfiguration in my router? What
could cause such a behavior? Should I post some of the conifguration files
here?
- Is there any test that could help me pinpoint the exact source of the
problem?
- Which FM should I read?
Thanks a lot for any hint...
och
