OLE Performance Factors with Windows 3.1

• Microsoft Windows operating system versions 3.1, 3.11

SUMMARY

In Microsoft Windows operating system version 3.1, objects are passed between applications through memory with OLE version 1.0; therefore, memory availability is often the limiting factor for OLE operations. Using an embedding function (such as OLE drag and dropping) with large objects can cause duplication of data and require storage space.

MORE INFORMATION

Locality

To perform OLE functions, both the client and the server applications must be on the same local machine. The information (that is, the container document and the source files) can be stored on the file server.

Embedding and Packaging

Embedding and creating packages by dragging and dropping an object from the File Manager creates a copy of the object, which is stored in the container document. Embedding large objects (such as sound) duplicates a large amount of information and requires storage space. Embedding and OLE drag and dropping large objects requires large amounts of memory.

Memory Limitations

All objects are passed through memory in OLE version 1.0. This places limitations on OLE operations especially with low memory conditions.

Size of the Object

The size of objects being embedded or linked is limited by the system resources (memory and storage) only.

Number of Linked or Embedded Objects per Document

The number of objects that you can embed or link is limited by the system resources (memory and storage) only.

Activation Time for Objects

Different servers have different times of activation. For example, a large spreadsheet application has a longer activation time than a specialized mini-server. Also if the server is already running when you activate an object, the activation time is significantly shorter.
