Google Web Decelerator???

[PaulFXH]

Hi
Over the last couple of days, I've noticed my DSL download rate had
dropped to only about 10% of what it used to be.
My ISP said no problems were evident with my line and asked me to check
the active connections (DOS Prompt>Netstat). This showed an astounding
number of TCP connections (more than 50).
So, following this revelation I proceeded to systematically shutdown
running applications to see what was the cause of this. Surprisingly,
the culprit was the Google Web Accelerator (Freeware) which I had been
using for about 6 months.
Shutting this down, returned the number of active TCP connections to
less than 10 and, more importantly, returned the download rate right
back to where it should be.
But why did this app suddenly turn nasty in the last few days? Is it
conflicting with something else on my machine?
Anybody else got a similar experience they'd like to share?

TIA
Paul

I don't use accelerators so I can't help there but...The next time you
need to check your net connection, try Wireshark (wireshark.org/). It
was known until very recently as ethereal.

Wireshark's help me nail a couple of app-related behaviors w/o the
hassle of turning off suspects. As an added bonus, it's great for
learning about how your os & apps behave via network protocols.

fwiw,

Agreed. It slows down my internet, when I used Google Web
DE-celerator....


But...
It's still in the "works" at Google Labs...so I say give it some time!!

Having used some p2p and torrent applications in the past I have seen that
too many tcp connections have a retardation effect on the connection

This is partially because of the limitation of XPSP2 to 10 half open
TCP connections (this can be increased with a known patch) that they
added to SP2 for security reasons (they wanted to limit virus exploits).
But it is also because all the connections are trying to reach their
locations
to transfer, and because they are so many none of them is able to actually
do the transferring!

Remove that web accelerator. Those programs offer nothing. If you want some
tips on how
to optimize your web experience post here and I might give you a few
pointers.

Thanks for this tip, Craig. I checked out Wireshark and this is an
impressive tool. Sure beats the socks off Netstat.
Even though I can claim to understand only a fraction of the
information it provides, it gives an intriguing opportunity to discover
a lot more about what's coming in and going out of my computer.

Thanks for the reply.
What exactly was slowed down on your internet (downloading, uploading,
browsing in general?).
My experience is that my internet connection became overloaded just
very recently despite having used this accelerator for more than 6
months. It seems that a conflict suddenly developed between this and
something else on my computer.
Is your experience similar or has the Google Accelerator ALWAYS kept
your internet slow?

Hi Ken
Although I was unaware of this limitation I have seen in excess of 50
active TCP connections at one time on my computer with WinXP SP2.
However, I've Googled for it and seen that you're correct. So, how
come....???
As for the patch to overcome this limitation, why would I ever WANT to
have more than 10 connections if this is simply going to slow all of my
internet activity?

My problem seems to have been that something "upset" the Google Web
Accelerator causing it to induce an avalanche of TCP connections
leading to a dramatic slowdown in internet speed (Beware: this is a
well-intentioned, but totally amateur, diagnosis).

But it is also because all the connections are trying to reach their
locations
to transfer, and because they are so many none of them is able to actually
do the transferring!

I should mention that I also use the Intel Accelerator. I really cannot
say that I have seen any significant improvement in my internet speed
as a result of these accelerators. You'd really need to have two
identical (and identically configured) computers operating
side-by-side, doing exactly the same things in order to verify that
there is a difference which is rarely an option for the home user.
I believe I left them on my machine simply for the "feelgood" factor of
having freebies from such renowned names as Intel and Google helping my
browsing.
Yes, I would certainly like to hear your views on how to optimize my
web experience without accelerators.
