C# Windows Form, Windows 10. using Dapper DLL. a very small table, only 80 rows and about 10 columns. doing this query: Select * from House order by Territory,TSeq ASC. Territory is a string, TSeq is an Integer. on a windows Form in the program, i do the Select using Dapper. take the result set into a List, then write the rows to a ListView. In the /bin/Release/ folder, this loads the ListView immediately. using SQLiteStudio, this Select takes .07 seconds. however, when I copy the /bin/Release/ folder with the exact same exe/dlls/and DB, to a folder on the Cdrive or Ddrive, it takes about 5 seconds to populate the ListView. I've tried with and without all the PDB/xml/config files, and on different drives and folders.. it runs slow everywhere but in the /bin/Release folder. ??? maybe this is a C# forum question, but I can't see what the difference would be between the Release folder and some other folder. thanks for any comments... eric
