US Internet Speeds

News, Warnings | Posted by Dennis March 17th, 2012

Well, I’m not surprised:  the mid-west, Oklahoma included, lags behind the rest of the US in bandwidth, according to a study by Pando Networks (see map).  Growing up I always said that Oklahoma was ALWAYS behind the times by about twenty years.  It’s not as bad now, but still… maybe 5 years?  :-)  In a recent study they sampled data from all over the continental United States, and found big differences between our state and California, for example.  Rhode Island was at the top of the charts, while Idaho hit dead last.  I haven’t seen the push that I expected in the last few years towards fiber optics.  AT&T was actively installing fiber networks for awhile, but I don’t see as much activity lately.   I think part of that is because the push is towards cellular and wireless networks.  But consumer’s thirst for more bandwidth is outpacing the 3g and 4g expansions, so it seems prudent to continue building fiber networks.  I think that eventually the cell companies will have to tie their towers to a really big data pipeline like fiber offers.  Here’s the source article if you’d like to read it.

Memory

Helpful Hints, News | Posted by Dennis September 12th, 2011

You may have heard about the breakthrough in Alzheimer’s treatments, but what about your PC?  I have a lot of customers that think adding RAM will cure their computer’s problems.  Usually it’s slow, and they want a quick fix (see my previous article about this).   Sometimes it CAN help, especially if your PC wasn’t engineered right in the first place.  First of all, there is a “sweet spot” memory limit for Windows;  XP = 500 Mb, Vista = 1 Gb, Win 7 = 2 Gb.  If you don’t have at least this much memory, you should add some.  But for a long time now there’s been a cool thing called DUAL CHANNEL MEMORY on the mainboard of PC’s.  It means that the stuff that gets processed via RAM has twice the pipeline to do so, and can REALLY give your PC a boost.  Cheaper equipment will often have a single stick of memory installed, which is just silly given how cheap the chips are these days.  If you go configure a new computer on the Dell site, for example, you might notice a choice between 2 sticks vs one.  ALWAYS GET TWO!!   It’s better (faster) to get two sticks of 1 Gb RAM than a single stick of 2 Gb, even though it’s’ the same amount of physical memory.  Go figger…

Speed up your PC

Helpful Hints, Warnings | Posted by Dennis August 26th, 2011

A slow PCI see lots of ads and products that claim to speed up your PC.  A slow computer is one of the common complaints that I resolve for my clients.  I can tell you that THERE IS NO SINGLE, SIMPLE solution to this.  BUT there are lots of things you can do/check.  First, make sure it’s not just psychological.  Did you recently get a new PC at home or office that is really fast?  Otherwise, did it suddenly get slow?  You might have a ‘critter’ of some kind, so run virus and malware scans.  Check the Task manager (CTRL-ALT-DEL) performance tab to see if your CPU is working hard.  If so, it’s busy doing something in the background that you may not know about.  Click the process tab to see which program is so busy.  You can also run MSCONFIG to remove software that runs when windows starts.   Otherwise, if it’s hardware, you need to find the one thing that’s slowing it all down.  See, the slowest piece will limit the chain of events, kinda like the rate limiting reaction in chemistry.  The windows 7 performance index is a good place to nail this down.  The lowest scoring hardware is your rate limiter.  Be aware that anything internet related should also include your BANDWIDTH, or internet speed, in the analysis.  You can test your internet speed here.
