Tutorial or Site for Improving LAN througput ?

zapp22 · 19 Dec 2013

Guys I would really appreciate a response or two.
I need to learn some best practice for identifying/remediating bottlenecks on simple office LAN's. The norm these days in small office is that most of the connections are wireless, most of the embedded resources are wired [though that is changing]: fax, printers, etc.
When I do spot checks, I find really huge variances in throughput for the users and am baffled by this.

One specific I wonder about: Some of these NIC's/Chipsets/wifi adapters etc are broadly used and well-understood. For some, there are certain "must do" changes in configs that greatly help the average user-experience. If anyone knows of a resource where such "tweaks" are collated for the most common chipsets and/or devices, I would really appreciate a notice of such.
As to the tougher issues of interaction between routers/bridges/AP's, I am really poorly educated and need to climb the curve.

thanks

Hi there,

Network bottlenecks - make sure that you are using good network switches, at least gig switches, this goes with the NICs. The ethernet cables needs to be at least Cat5e or higher. Heavy utilization of File Servers, databases, etc... also contribute to bottlenecks. Check the hardware specs of your Server. You must have at least RAID 5, if your server(s) is/are heavily utilized. We have 2-RAID 10 rack servers as these 2 Servers (for ERP system and Exchange Server).

There's also internet bottlenecks - make sure that you have a good amount of bandwidth subscribed from your ISP. A modern/sophisticated dual band router is a must, this goes with the Wi-Fi cards. Be aware if the Users are doing non-related business activities hogging your data, this is a big No-No!

Some helpful Technet reads on how to identify bottlenecks and correct them.

Hope this helps.
