Do you have any recommendations for improving the performance of Structural Engineering Library when Project Files are accessed across a Local Area Network?
The first recommendation would be to click Settings > General Settings, and then select the option to "Use memory mapped Project Files during program operation". This option was specifically implemented to improve performance when Project Files are accessed across a LAN.
If this option does not provide a satisfactory solution, please refer to the information in this document for some suggestions on how to improve the configuration of your LAN: http://www.enercalc.com/pdf/ENERCALC_Network_File_Performance_Issues.pdf
