Hi John That seems a bit slow to me but when it is set up and running and the price is right it should be fine - I mean, 73 seconds, should it matter? /gustav >>> jwcolby at colbyconsulting.com 28-08-2009 19:43 >>> Gustav, I have Hamachi already in place on the client's server as well as my system. I routinely remote desktop in to his machine already. I had set up the path to the data files (in / out) as a SysVar and so I mapped his remote database directory (on his server) to y: on my dev machine here at my office and changed my sysvar to point to the new location. I then ran the existing Access application. I set up my timer class to time the import, which uses a simple docmd.transfertext to pull the data from the CSV file into a first stage processing table. Looking at five different runs, the time to import 835 records from a CSV file into a local table, across the internet using Hamachi is Import From File took 72915 Milliseconds Cleanup of raw data took 2354 Milliseconds Import From File took 59250 Milliseconds Cleanup of raw data took 4319 Milliseconds Import From File took 23369 Milliseconds Cleanup of raw data took 3307 Milliseconds Import From File took 23354 Milliseconds Cleanup of raw data took 3447 Milliseconds Import From File took 23353 Milliseconds Cleanup of raw data took 3181 Milliseconds I had done a couple of runs before I set up the timer and the times there were approximately 24 seconds as well. So the "normal" time is around 24 seconds, but it can be quite lengthy as you can see, 73 seconds in the worst case so far. What was going on during those longer time imports is unknown. The server is being used to store these scan files as well as process them. OTOH the server is also a 750 mhz pentium machine, pretty slow as servers go. We have a new server ready to go online. And of course this assumes fast internet at both ends. I also built a button to allow them to open the source CSV files in notepad. That only took Time to open the file in Notepad 4930 Milliseconds Time to open the file in Notepad 4290 Milliseconds Time to open the file in Notepad 2855 Milliseconds Time to open the file in Notepad 4274 Milliseconds So obviously the import process itself is taking a fair amount of time. Anyway... I would guess that for a small company like this, a Hamachi VPN to a central server is going to work quite well. Low cost, reasonably fast, and easy to set up. John W.
