I had problem of slow browsing speed this month on dataone home 250 connection
found tcp optimizer settings to solve it in speedguide forum hope sharing this may be useful to someone else
General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1500 (1492/1454/1480 test and find the optimum mtu of your connection I am now using 1480)if u using ppoe 1492 is recommended
for help see SpeedGuide.net - TCP Optimizer
TTL - 64
TCP Receive Window - blank
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - uncheck
Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
(values which are different from default in red )
Then select "Apply Changes" and reboot to take effect
now there is much improvement in browsing speed (in my case -xp sp2 &ppoe)
you can try it as tcp optimizer has restore function you can revert change
if u done firefox speed increase tweaks also it will reduce page load time further (I know ff tweak must have been here before for those who may not noticed I include it also)
Type “about:config” in your firefox address bar.
Search for the following settings:
1. network.http.pipelining
Set to true
2. network.http.pipelining.firstrequest
Set to true
3. network.http.pipelining.maxrequests
Set to 32
4. network.http.proxy.pipelining
Set to true
5. nglayout.initialpaint.delay
Set to 0
Its very likely that you won’t have an entry for network.http.pipelining.firstrequest. Thats ok. Just add one.
Right-click on the preferences list, select ‘New’ then select ‘Boolean’
On the first prompt, type:
network.http.pipelining.firstrequest
On the second prompt, set it to ‘true’
if you won’t have an entry for nglayout.initialpaint.delay
Right-click on the preferences list, select ‘New’ then select ‘Integer’
On the first prompt, type:
nglayout.initialpaint.delay
On the second prompt, set it to ‘0′
restart ff
if u you want revert these then
run firefox -p
create new profile and delete old
