The Document Transformation Server consists of two software modules: the Standalone
Document Transformation Server and the SkyVault Transformation Client.
The Document Transformation Server is sold as a SkyVault module that is enabled with a
license key:
- The Standalone Document Transformation Server runs on Windows and takes care of the file transformations.
- The SkyVault Transformation Client runs as part of SkyVault and communicates between SkyVault and the Standalone Document Transformation Server.
Disc I/O bandwidth
Microsoft Office transformations are I/O-heavy, and so on some solutions, I/O contention can be a performance bottleneck. When multiple Word conversions occur in parallel, performance can suffer heavily from poor random read and write speeds.
Using an Amazon EC2 instance c3.2xlarge, the I/O metrics are as follows:
- seq. read speed: 131 MB/s
- seq. write speed: 83 MB/s
- random qd32 read speed: 10,4 MB/s
- random qd32 write speed: 3,8 MB/s
