How To Improve Performance

To achieve optimal performance with PHDwin, we recommend the following upgrades, in order of importance:

Dedicated server for your PHDwin databases
Hard Disk – upgrade to a Solid State Drive for faster read/write speeds
Processor – upgrade to at least an i5 or i7 quad-core processor to improve the speed of economic runs. PHDwin’s economics engine is capable of parallel processing and efficiently using all cores available on the computer.
Network – upgrade to a Gigabit connection to improve data transfer rates
Memory – upgrade to at least 32 GB RAM to ensure smooth performance, particularly with larger datasets.\
Upgrade to Full SQL Server – Recommended for data sets of more than 5,000 cases.

By providing a dedicated server with solid state drives, multi-core processor, and gigabit network connection, you can significantly improve the speed and efficiency of PHDwin.
