Hi all,
I wondered whether anyone might be able to help me with a problem. We are using iAnywhere.Data.SQLAnywhere.v3.5.dll versions 11 & 12 to connect to a Sybase database over a LAN which is fast and reliable. However we have recently been using this over a WAN with both Sybase and other drivers. We have noticed a significant decrease in performance when using the Sybase ADO.net driver in comparison to other database platforms and drivers (such as SQL Server's ADO.net driver). The performance issue has been tracked to the Fill method of the Data Adapter. Even small retrieve statements can take seconds compared to near instant retrieves when connected over the LAN or indeed those of other drivers over a WAN. The performance difference is substantial between the Sybase and SQL Server drivers, with SQL being much much quicker. Is there something we are missing, or is this a scenario not supported by Sybase?
For reference we have also confirmed this issue to be the same with the latest version of Sybase v16. Any advice or comments much appreciated.
thanks
Ach
