INF: Poor Response Time Returning Multiple Mainframe Records

• Microsoft OLE DB Provider for AS/400 and VSAM, version 1.0, included with:
  • Microsoft SNA Server, version 4.0

SUMMARY

When a consumer or client program, using ADO, asks for multiple records from an IBM OS/390 VSAM file, the response time is very slow and increases with the number of records retrieved.

To improve the response time, set the CacheSize property of the ADO recordset to a reasonable value greater than one (1), which is the default.

The CacheSize property is described in the ADO online documentation, which Can be installed with the Microsoft Data Access Components.
