Number of I/O Requests Depends On Amount Of M |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: A customer sends a print job to a Novell network printer from WP 5.1 DOS. The customer is running WP on a 286 computer, and 36M of network traffic is generated by the print job. The same file sent from a 486 computer with 8M of memory only generates 600K of traffic on the network. Solutions: The 486 computer made fewer I/O requests from the server because of the amount of additional memory available to WP 5.1. When the /NE startup option is used on the 486 computer, a similar amount of traffic is generated because WP no longer has access to the additional memory. How/Why: This situation was tested using an in-house utility that tracks I/O calls made on Int21. The 486 computer made 114 I/O requests, while the 286 computer made 427 requests for the same file. The file that was tested contained a 10x25 table with a graphics box, no text, and no font or attribute changes. If these additional codes had been added to the file, the amount of I/O on the 286 computer would have increased exponentially because the 286 computer did not have any additional memory available for rasterizing, etc. |
