When executing queries over an HTTPS (SSL) connection to an Analysis Services 2000 Server, the query performance may be considerably slower than when the same query is executed over an HTTP or native TCP/IP connection to the server.


The module that handles HTTPS connections to the Analysis Server calls the WinInet InternetReadFile function for each individual protocol stream object/property, whereas TCP and HTTP connections use buffering when reading data.


To resolve this problem, obtain the latest service pack for the Microsoft SQL Server 2000 (the Analysis Services Components - Sql2kasp1.exe). For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
