>>Most (so I guess yours too) notebook PCs have very slow hard drives when compared to workstations.
>>
>>So, especially if your application does do a lot of I/O, most particularly on the local drive, then time can easily stretch.
>>
>>You may have to look for ways to reduce the I/O on the notebook HDs. Makes one wonder if you might even be better of using the server for temporary files.
>>
>>One other thing... it's true that VFP is not "optimized" for dual processors, but that doesn't mean that it doesn't/can't use them or that it will run slower just because it is on a dual processor. There was a thread here 3-4 years ago where, in a very specific situation, it was reported that an application ran better than 2 x faster on a dual than on a uni.

>>good luck

>>>Calling on all network/hardware guru's with my thanks in advance. Here is the problem:
>>>
>>>This is the about the performance of one of my (large) VFP programs on a network. Running my program locally (on one computer) the program takes seconds to complete (15 seconds). Running on a network with a fast connection it takes about 1 minute. Now the real issue. With two computers connected via the same switch to the same server they get different results(running one at a time and fresh boot of the server). Computer A is a desktop. Computer B is a laptop. Both report the connection as full/100T. The switch reports both are Full/100. The server is also full/100.
>>>
>>>When the program runs on Computer A task manager reports 19-29% CPU usage and network usage peaks to 7%. Finishes in 7 minutes. Network usage is almost flat line at 7%.
>>>
>>>When the program runs on Computer B task manger reports 19-29% CPU usage and network usage peaks to 20%. Finishes in 1 minute. Network usage bounces a lot.
>>>
>>>Computer A is a dual AMD 1900. intel pro 100 NIC with 1Gig of ram and 29 processes running.
>>>
>>>Computer B is a intel 3.0 realtek NIC with 256Megs and 32 processes running.
>>>
>>>Both computers start the program from the server. 6 minutes is a big gap and I can't see why. I have loaded the latest NIC drivers for Computer A and nothing changed. Both computers are running XP with the latest patches. Task Manager reports the swap as not being used. Both report memory usage as approximately 157K during the program.
>>>
>>>Nothing was done to any register setting for either of the computers i.e. Oplocks or caching.
>>>
>>>John
