Fast internet connection, SLOW BROWSER!

Ok, running an iMac 10.5.4, 2Gigs of RAM, no problems before.

I have 3 machines hooked up through my router, this MAC, a 4 year old piece of junk PC laptop, and my PS3.

For whatever reason the laptop is (we have a 10+MBPS connection) blazingly fast surfing the web (both MAC and PC are using FireFox2, not 3), its far faster than the Mac.

What happens is, lets say on both I load a fresh page, the PC will load it up instantly, the mac will wait a few seconds while it says "looking up, or transferring" in the browser and then load, but it loads noticeably slower (about 2-3, sometimes 5-8 full seconds) than the PC.

Is there any settings in the Network I need to fiddle with? The PS3 and the PC are working fine through the net, but for whatever reason the Mac is slow going on the browser. I have tried Safari 3 and Firefox 3 and they both do the same thing!

Its very frustrating because the Mac is my main computer, the laptop is in another room and its never used for web browsing. I would really appreciate any help on this. Its driving me nuts.


(its a wired linksys router).


Look at the bottom loading bar thing, this is what it does to me all the time on the MAC, but not on the PC and the PS3 gaming is fine.....

The problem could be related to DNS. DNS is the system that translates from a computer name (e.g. Apple) to its IP address (e.g. 17.149.160.10). Each web page viewed will need to do this translation since the actual data transfer is done via IP addresses, not names. Usually the IP address is cached (for a while) after the first time it is looked up via whatever DNS server you have configured your Mac to use.
Many (most?) routers will automatically set up the DNS servers without you having to manually enter them in the DNS server slots in the TCP/IP section of Network Preferences.

One way to check if the slowness is related to DNS is to access the web page via IP address in the browser - e.g. instead of typing in Apple in Safari, type in 17.149.160.10

You can see what DNS servers are currently configured via the following command (in a Terminal window):

cat /etc/resolv.conf

Another diagnostic test that might yield useful info is the following command (in Terminal):

/usr/bin/curl $@ -o /dev/null -w "dns: %{time_namelookup} connect: %{time_connect} pretransfer: %{time_pretransfer} starttransfer: %{time_starttransfer} total: %{time_total}\n" Apple

This will access the web page at Apple (obviously you could substitute other URLs) and print out timing info for the various stages of the data transfer. The first number printed at the bottom is the number of seconds taken for the DNS lookup. This command only transfers the HTML of the base page - it doesn't transfer images on that page, etc.

New issue, I must say.... on the PS3 it said twice now, NO ETHERNET CABLE CONNETED.

Never had that before, this router is proving problematic.

Ugh.


Anyway, so that 2nd test came out like this:

Quote:
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
dns: 0.029 connect: 0.085 pretransfer: 0.085 starttransfer: 0.156 total: 0.156
Macintosh:~ Sandy$


I opened up my DNS to different #'s and they show up on the Terminal, so I have them right on my PS3 and my Mac.

Could that have helped any?

I'm hoping I don't need a new router or anything, hopefully this works for me. I don't know what else I can do

I assumed you had no worries with the router.

What has changed recently? New router?

Plug your Mac directly into your modem if you have a separate modem and see if it is fast/normal.

Try different ethernet cables.
Switch them if you don't have an extra one.

I hadn't changed the router in a long time, so nothing there. I have UPnP available on it, so that the PS3 could achieve a NAT TYPE 2 properly. (which is seems to)

I'll try going directly through the modem.

If nothing has changed, you had no issues with the Mac before, and yet suddenly you have issues, something must have broken or been changed.

Same thing as before....


But I tried changing the DNS #s to 208.67.222.222 and 208.67.220.22, and it seems to be better. Someone had told me this is what I should try as well..... so far... seems ok.

Now I need to figure out that PS3 problem... maybe this router doesn't like it.

Where is that last zero?
typo?
type it in again, no spaces......

The DNS Server addresses for OpenDNS.com are:
208.67.222.222
208.67.220.220


Additionally your resolve looks 70% faster then mine?

Is the router you use very old? If you bought a cheap router, chances are it is not designed to last very long. Personally, I've had 4 wireless routers over the past 8 years.

You say you are using FireFox.

Type about:config into your browser. This should bring up and extensive page of editable preferences for the browser. Your PC version may have different default settings.

If you Google about:config, you can find some pages on optimizing the browser for speed. This works with any mozilla based browser. Some versions were defaulted to run smoothly on 56K modems, not high speed.

I can't give you the exact settings as I have only been using this technique on my classic macs running WamCom Mozilla and I do not know if the settings are the same. Scroll down until you reach the network settings. I upped the maximum number of connections and turned pipelining on. As I said, I do not know if this is applicable to you.
