[RESOLVED] Slow Browser Response

Windowx XP, SP3
1.85GHZ AMD XP
2GB RAM
120GB bootable HDD with plenty of space
IE6 and Firefox 3.0.5


Nearly every web site I visit gives me a stop & go, jerky load; random parts of pages (images and text) will load quickly, others will choke or not load at all. Sometimes pages don't load at all: "Too long to respond."

I can ping my router, my two DNS servers, and various web sites with acceptable respons. Last ping of a web site showed : 42MS and 0% packet loss after 200 pings. I get good pings even when pinging a site that's choking in one of my browsers.

I've rebooted the computer, reset my router (not wireless). Also cleaned up junk with CCleaner. I've also disabled my ZoneAlarm firewall and get the same results.

The only thing that's happened between yesterday and today is I ran a full scan of my computer using Spysweeper, quarantining suspected junk.

I'm getting ready to run Hijack This and other spyware utilities, but wanted to tap the knowledge in the meantime.

Print these instructions out.

Thanks for the response, Train. I ran a few favorite utilities and found nothing of note.

Anyhow....turns out the ISP in our small town installed a bandwidth shaping utility to throttle connections from each customer's static IP address. He'd limited it to 25 simultaneous connections per household to control the bandwidth use of peer-to-peer households.

The problem with limiting connections wholesale, as I pointed out to him in an email, is that one can have a multitude of simultaneous connections simply by visiting a single web site. I sent screen shots of the 24 connections established simply by visiting the Los Angeles Times home page and then clicking on the jobs link. Add a chat client and maybe some POP mail, and you're well over the 25 limit with barely any bandwidth use.

He increased the number of connections to 75. There's probably a better way for him to attack the bandwidth use problem, but I'm not that geeky ;-)

San Antonio's population is well over one million. What is your definition of a city? :)

I know this is not it.

LOL. Actually, I live outside of San Antonio in a nice little town called Castroville. Population is just a little more than 2,600. The ISP delivers broadband service via line of sight radio. It's a two-man company that's doing okay. The alternative is dial-up or satellite (which I've heard stinks).

Wagontire eh? Can't say I've been there or even heard if it ;-) I've been to Harmony though
