Acer Aspire 5740z, Windows 7x64, 4GB RAM, Dual Core something-or-other.
If my laptop has been asleep/hibernated for longer than fifteen minutes then:
* bbc.news.co.uk or digitalspy.co.uk (or in fact most web sites) causes a long delay. Nearly half a minute before the web page loads.
* forums.thinkbroadband.com and theregister.co.uk are not effected.
* No matter how long the laptop is left showing the desktop the above two statements are true.
* If the browser is launched then left doing nothing for half a minute the delay doesn't occur. While waiting for a 'delayed' site you can open undelayed sites quite happily. After the delay period is over everything is fine.
* (this one is a kicker) it affects both browsers on the laptop (IE and Chrome) individually. That is - having experienced the delay with Chrome you can open IE (many minutes later) and it suffers the same delay.
* The delay doesn't occur if you close the browser then restart it.
* The delay doesn't occur if you put the laptop to sleep then wake it again within ten minutes or so.
It seems to me that something that both browsers are relying on for certain web pages has a long start up period. It is needs to restart if the laptop sleeps for more than about ten minutes. Once it's got going for a particular browser if you launch a different browser it has to be started again.
Solutions tried to far:
* Networking diagnostics - everything is fine. No surprise since as long as you don't visit an affected site within the first half minute everything is fine plus while one site is a delayed other sites are not.
* Disable Avast - no difference.
* Disable ad blocker - no difference.
* Remove shortcut to local network folder from desktop - no difference.
* Analyse network traffic with Wireshark - no obvious difference other than timings. You can see an approximately twenty second drop in traffic and the gap between connecting to the site and getting the response. So confirmation of the problem but no explanation.
* Analyse process activity using SysInternals ProcMon - similar to analysing network traffic although it's scary how much Chrome is doing under the covers. It spends about a tenth of a second apparently looking for DLL injected code and makes a gob smacking number of registry queries most of which fail because the key isn't there.
So I'm stumped as well as irritated. After all what's the point in having a laptop sleeping by your side so that it can be ready in two seconds if you have to wait an extra half a minute before you can browse? For what it's worth the laptop is pretty much only used for browsing. I'm way past the age of wanting to install lots of [censored] just to see what it's like. I get to tinker with OSes in my day job so my main machine at home has almost nothing installed on it.
Oh and the server upstairs (also Win7) doesn't suffer from this. It has its own performance issues because it's a 1GHz Atom with only 1GB of RAM but within the constraints of 5w power consumption it runs fine
