Hello jirka,
Thank you for your question.
I searched for [dsl latency] and found some very interesting pages for
you:

"What Earthlink's Customers Aren't Being Told
In an effort to reduce costs and become profitable, Earthlink has been
cutting corners. They pay their employees low salaries, they keep the
callcenters understaffed, and they they don't upgrade their network to
provide sufficient service to their DSL customers. The following is an
email sent by an Earthlink employee in the TRON (aka DSL tech)
department:
--------------------------------------------------------------
Subject: "Slow speed / latency / packet loss, affecting DSL users in
the following markets LAX / CHI / ATL / NYC"
Wide spread slow browsing / latency / packet loss issue, There is
nothing that opening a Trouble Ticket with TRON can do about this
issue, its in NetEng's hands..."
They continue to document particular areas with problems. Since you
did not mention where you are located, i can not be certain if your
location is mentioned. But interesting to see you are not alone.
He continues:
"...In most cases these are NOT Vender issues, if possible, Coved
users, check the DSLAM stats if the users have good readings then its
most likely not an issue with the Vender. Explain that we are aware of
the problem and working to resolve it.
Now for the technical info, These Redbacks are at capacity on their
ENET ports, at around 75Mbps they start to discard packets, and it
only gets worse as the traffic rises. Most of these Redback are
peaking at over 80Mbps, and discards of over 1,500/sec.
The current situation seems to be that NetEng is waiting on an Updated
AOS revision that allows the spanning of single context traffic over
multiple ENET ports. This will allow them to split the traffic up over
2 or more ENET ports to solve the capacity issue.
So what can we/you do about this now? Nothing, we are in the hands of
our Network Engineers now, and they seem to be moving very slowly on
this... "
"...According to this email, Earthlink's Redbacks are at capacity
which is causing the slow browsing, latency, and packet loss that
their customers have been experiencing. Earthlink's support website
has the following to say about the issue in California:
Currently some xDSL customers in Los Angeles, CA and surrounding areas
may experience some latency and packet loss. Our engineers are
currently aware of this issue and are working to correct this as
quickly as possible.
Earthlink's support website says that their engineers are "working to
correct this as quickly as possible" yet Justin says they are moving
"very slowly" to fix the problem. When I asked another Earthlink
employee what he thought of this email and the accusation that
Earthlink's Redbacks are at capacity, he agreed that it was more than
likely true, adding "Earthlink tends to run a bit faster than its feet
can carry it."
So, in fewer words, certain locations for Earthlink are at or above
capacity and need to be updated / upgraded / or more hardware added to
provide the throughput their customers desire. You might browse this
site for additional information
As a longtime DSL user, I do not believe that the problem you describe
is a timing or "time out" issue. It is rather the providers equipment
waiting until it can deal with your requests.
Broadband Reports is an excellent resource to learn more. This page
offers very in depth details on DSL and Cable speed and problems that
can occur. It is recommended reading:
http://www.dslreports.com/speed
Learning this, I could target my search a little more specifically to
[earthlink +dsl +latency OR "speed problem"]:
Another Broadband page:
http://www.dslreports.com/faq/2224
EarthLink DSL FAQ» How can I tweak my connection for better speed and
performance?
You may well find that the tweaks listed here are superior to the
software sent to you by Earthlink.
As with any hi-speed internet provider, some customers will be
ecstatic and never have a problem and some will never experience the
performance they thought they would receive. Sometimes it turns out to
be hardware, sometimes poor software settings and sometimes your house
wiring or phone company's wiring between you and your Central Office
- squirrels can wreak havoc on phone lines.
But, in your case, I strongly suspect the problem to be at the router
end of the connection and hope the above pages will provide lots of
insight for you.
Other great DSL pages include John Navas' pages:

I leave you with a haiku I found on my search at the Tech Support
Haiku Database:

Earthlink DSL?
Sure, your problem will be fixed--
When Satan ice skates.
Good luck regaining your connection speed!
