| + | |||
| + | 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| + | Another thing to look for is if your lan is running on outdated 10 Mbit hardware, instead of the newer 100 Mbit (or faster) hardware.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. | ||

| + | 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. | ||
