Saving is Slow in AutoCAD 2005

[cwade]

Ok, we have the follwoing setup:

Three Computers are connected to a DSL router that is connected to a hub that is connected to the server.

Three are on a switch connected to the hub serving the server.

One is connected to a switch connected to the hub serving the server.

And one more is connected to a hub that is connected to the server's hub.

The alst two are the only two that don't have issues, the others are:

1. Extremely Slow when opening drawings.

2. Extremely slow when saving drawings (on the same computers that hav problems, this is not an issue for 2004)

3. Extremely slow when going to plot.

I have searched high and low and all I can ever find are posts saying to search for the answer on other discussion groups, please if anyone can copy andpaste the answers if they find them or actualy answer the problems, I hope we can have a least one message with the answers needed.

Thank You

Why are all of these systems on separate switches attached to hubs? Unless you have a distance issue, this small of an office should be attached to the same switch your server is on.

1. Get rid of your damn hubs - they only slow things down. Switches are cheap enough that you should only be using switches. This ensures you have full bandwidth for every system on the network.

2. Unless your computers are over 100m from the server, you shouldn't be using other hubs or switches for this small a network. This network is bass-ackwards anyway. You should always have a switch at the center of your network (where your router and server are), and if you must, use hubs on the periphery. But don't do that. Use a small switch, not a hub: but even better, just hook up directly to the switch that the server is on.

3. Your DSL router should go into this central switch. (I hope you have a firewall on this router.)

Well, that should get you started. :wink:

OK, well the server is at the center, distance is an issue, we are doubling the size of our office and we will have about 20-30 computers on the network within a year. The DSL can't be relocated due to line issues, we only have one phone jack that works with the DSL connection, it has to be through a certain phone company. Why thier using hubs I am not sure, but really the ones that are still setup as they originally ere are the ones that are now having problems.

I would really go with, look at Marc's (powermarc) suggestions of your current network infrastructure....

If AutoCAD uses files etc from a network it will ping/connect with the network when it performs a number of different operations, if your network has issues/problems they will become very noticeable within AutoCAD itself (Delays; Slow responses to certain commands; etc).

The following threads contain information that relate to some of those network issues/problems that can occur within AutoCAD -

Have a good one, Mike

Again, I must reiterate, get rid of the hubs, especially the one the server is on. Use switches only from now on. Hubs are dumb devices that effectively reduce your bandwidth by half for every device that is attached to it. This results in having all of the network data sent to all the computers that are attached to it, whether it's meant for them or not. Switches actively manage traffic by only sending network data to the computer it's meant for.

If you are expanding your office, this is your chance to get rid of all the **** network gear you have now and and have your office wired properly. I should have been more clear about the distances you can traverse with wired Ethernet: it's 100m (328 ft.) maximum cable length from point to point, so you could have your DSL router attached to a small switch halfway between where it has to reside and a larger, central switch.

I don't know what your physical layout is there, but there should be enough flexibility in the cabling limit to get everything hooked up to switches. :grin:

Well, apparently this was attempted last night and we still have the same problems with AutoCAD, but now it seems to be random as to which systems are the slowest, incidentally the Internet is blazingly fast on all systems, but not AutoCAD, even when saving to the local hard drive.

Oh, also there is no lag in AutoCAD 2004, only 2005.
