| + | These are terrific ideas. And these issues can all arise on a system that does NOT have defects. | ||
| + | |||
| + | To these I would add, and reiterate, that if you have a defect, like a damaged LAN interface that is chattering (only one of several possible issues) you will have additional, spurious traffic on the wire that can virtually use up your whole ethernet bandwidth. | ||
| + | |||
| + | The only good way to see this stuff is with a packet sniffer. These can be got online as shareware, and run on another computer of course. | ||
| + | |||
| + | Without the tools, you can't see the problem. | ||
| + | |||
| + | Another thing to look for is if your lan is running on outdated 10 Mbit hardware, instead of the newer 100 Mbit (or faster) hardware. | ||
| + | |||
| + | It is not generally understood that if you load a lan to about 10% (sometimes less) that it will begin to develop excessive packet collisions that will bog it down terribly. Obviously moving to modern 100 Mbit hardware moves this problem way out. | ||
| + | |||
| + | Another thing is the use of old, inappropriate HUBS, instead of modern routers or switches. | ||
| + | |||
| + | Not only does a Hub repeat everything on every port (which the others do not) but the older hubs had very limited backplane speeds compared to modern hardware. And some had pathetic firmware in them. | ||
| + | |||
| + | Switches are really cheap now. Get a modern Linksys, 100Mbit switch instead of an old 10 meg, hamfest junker. | ||

| + | Do I dare suggest another important clean up protocol? | ||
| + | |||
| + | Clean out the TRAY down in the right hand corner!! This is something I learned as a beta tester for speech recognition programs. Those little utility applets consume a lot of processor bandwidth and steal valuable processing time from your really important applications. For example, the speech recognizer is programmed to spend x clock cycles deciding on what it thinks you said... and then types it. If Norton Utilities (I hate Norton stuff) is running and waiting to tell me that my hard drive is full, or my printer driver is monitoring the amount of ink on hand, ... well... those programs are stealing valuable clock type from your productivity applications. | ||
| + | |||
| + | I believe this is another place you can clean up your computer. So, clean up the tray, also. | ||
| + | |||
| + | Just MY take.\\ | ||

| + | |||
| + | The problems may all be related to excessive computer resource use. I recently had a similar problem with a non Ham situation and resolved it by doubling the RAM. | ||
| + | |||
| + | One thing to check is the CPU usage and memory usage using the Task Manager in Windows. This can give you an idea of what software is tying up the computer resources at any moment. If ther CPU usage is stuck on 100% then some programmes won't get a look in. | ||
| + | |||
| + | The other thing to remember if you are using Firefox is that the longer Firefox remains open the more resources it eats up. It's advisable to shut it down and restart it every now and again if it's being heavily used (particularly where there might be a RAM issue). | ||

| + | I am not an Omni VII owner (I own a K3), but I have followed this group with interest since its inception. I am surprised that during | ||
| + | this discussion nobody has mentioned this little gem of a program: | ||
| + | |||
| + | https://www.thesycon.de/eng/latency_check.shtml | ||
| + | |||
| + | It is used to check a computer's "deferred procedure call latency", which is a critical factor for good real time audio and video | ||
| + | streaming performance. The author also suggests using the device manager to search for offending device drivers while monitoring. Folks with TRIP problems would also be wise to join the [[https://groups.io/g/LP-PAN|LP-PAN Groups.io group]] as there is plenty of advice there on how to clean up computers for good audio performance. | ||
