Re: mirror a drive
G'day listers Thanks to everyone that offered advice, both on and off list. The end user ended up running Onyx in Automation mode, with the following ticked Repair Permissions Execute Maintenance Scripts Launch Services Mail's Envelope Index User Cache Whichever one did the trick, the system went from dog slow to super fast. Next weekend when my client can afford the downtime, we'll try and isolate the cause and repair.

Oh my, that dredges up horrible memories of the days when we were routing Appletalk (Ethertalk) across campus. Whenever they had to work on the routers, we had to run around and shut down every Appletalk device, because the first device to wake up on an Appletalk network is the network master, and seeds the network ID's for the rest of the devices. We had to make sure the router was the first device to wake up or face endless slowdowns and the router wouldn't route until we tracked down the rogue Mac Plus or LaserWriter that had woken up first and said, in their finest Al Haig impression, "I'm in charge here!", turned it off, broke the fingers of the user who had ignored the sysadmin's orders, and rebooted the routeragain. This fun routine made Macs EVER so popular. The MOMENT that Appletalk over TCP/IP worked, we stopped routing Ethertalk, and cheers erupted all across campus. I think we had a New Year's-like countdown for the router update. :-) It might be possible you've got something like that going on. Shut down everything that speaks Appletalk, and if you have a server or router that's speaking 'Appletalk', make sure it's the *first* device like that your turn on; otherwise just find the fastest Mac speaking Appletalk in the network and make sure it's first. There's a nifty application called Trawler (or Trawl, I forget, this was the mid 90's) that will diagram and identify devices on Appletalk networks, but it's been a dogs age since I've seen it in the wild.

Re: mirror a drive
G'day again listers. New problem. To ensure that the HP printer was causing the problem we re-installed it on AppleTalk. Sure enough the server access slowed down again. Un-installed printer - still slow Turned off AppleTalk - still slow Re-booted - still slow. What on earth is going on, is there perhaps a preferences file causing this? Any ideas welcome, we're at wits end.

Re: mirror a drive
G'day Dan Situation: a mail room getting HEAPS of artwork that has to be printed on a tight turnaround time schedule. 30-40 emails per hour. The email and art has to be date/time stamped and archived to the mac AND the server on a network. For some reason the network is @#$% slow. We're talking 1 minute 20 to save 3 files. Latest situation in last hour. We've compared the performance of the power mac to my iMac 8000 miles away (I'm the author of the Applescript handling the printing/saving) and discovered that the end user had a HP laser running on his power mac using AppleTalk. We removed the printer, turned AppleTalk off (and set to automatic) and now the server is nearly as fast as the external drive. We can turn AppleTalk back on, and still maintain the speed as long as the printer is removed from the printer list. New Question. Can we do anything to use this printer and maintain speed?

mirror a drive
G'day I've got a bit of an OT . I'm trying to save multiple email, rtfd, and Zip files to a NAS server about 30 times per hour. The saving to server is proving very, very slow compared to saving the same files to an external hard drive off of the power mac. Time is critical, and the server is taking about 1:10 extra time per each group of 3 files saved. What I'd like to do is try mirroring the external HD to the server and update the mirror every time a file is added to the external. Is there any way to do this, OR is there something I should take into account to speed up the server.
