[WinMac] Slow NT server copying
Tony Green(tonygreen[at]mindspring.com)
Does anybody know what would cause slow copying from a Macintosh volume on an NT server to a beige desktop Mac G3 running Mac OS 8.1? Copying performance varies widely for no reason I can think of for as long as we've had this server and we've tried to find the culprit, but no luck so far. Today it's running about 2 meg/minute, so I thought I'd ask again. I've tried most of the tips at the Macwindows site, but the problem is very inconsistent. Most of the time, it's fine, but when it's not... we don't know "what's different."
The server is a Compaq 850R (single 200-MHz Pentium Pro) with 160 meg of RAM, 2 gig internal and two 9 gig Seagate external drives. NT 4.0 SP3 (I have the SP5 CD but haven't installed it yet). The hubs are a 24-port and a 12-port 3Com SuperStack II dual-speed units. Other hardware includes a Shiva LanRover and an AIT tape drive. There are three Macintosh volumes on the server.
There are about 20 client machines mostly beige G3s running 8.1 with some HP Vectras running Windows 95 OSR2. The Macs have 100 Mbit Asante Ethernet cards set to full-duplex.
We have Backup Exec but the maxfiles registry key is correct. The screensaver is set to blank screen.
What seems odd is that CPU usage is quite light. Task Manager is running 1-5% usage, System is around 5-8%, SFMSVC is using 0 K memory and 0% CPU (does that sound right?). None of the other processes show any CPU usage.
Total memory usage is 132284K out of 394020K (physical RAM plus paged memory).
The server was restarted yesterday.
We also have intermittent problems with Mac users hanging at logon, but logging on with administrative privileges fixes that.
Does anyone have any suggestions? Is it simply a matter of adding more RAM? If it were slow ALL the time, it might be easier to fix.
Thanks!
