>>A customer is having an issue of VFP9 application being slow (when used from desktops). The IT guy sent me the following message:
>>"The server is located in our corporate data center with slightly more latency, about 19ms, that doesn't seem like it should be this slow though."
>>Is 19ms latency very bad and could cause the application being slow? What are the typical ranges of latency?

>19ms points to something like a dedicated internet connection, as Al already described. Working "file handles", which vfp does with dbf/cdx/fpt data stores runs not well with that. Either get a real server backend or use remote access to run vfp instances on the net where the dbf data is sitting. If you already use a real server (why no info entered, which clearly is relevant??), try to replace chatty exchanges with chunky ones in your app

This customer chose to stay with VFP database/table; therefore no 'real server backend' (even though I offered SQL Server).
As I mentioned to Al, the customer is moving the server to the local environment. Hopefully this will improve the performance. I will post here the result.
Thank you.
