Workstation uses a memory trimming technique to return unused virtual machine memory to the host machine for other uses. While trimming usually has little impact on performance and may be needed in low memory situations, the I/O caused by memory trimming can sometimes interfere with disk-oriented workload performance in a guest. To disable memory trimming, select Disable memory page trimming.
Workstation uses a page sharing technique to allow guest memory pages with identical contents to be stored as a single copy-on-write page. Page sharing decreases host memory usage, but consumes some system resources, potentially including I/O bandwidth. You may want to avoid this overhead for guests for which host memory is plentiful and I/O latency is important. To disable page sharing, select Disable memory page trimming.
Select Log virtual machine progress periodically to increase logging information for debugging and troubleshooting purposes. By checking this box you do not have to edit a configuration file or restart the virtual machine to extract more detailed logging for technical support.
