Performance Enhancement in MicroStation CONNECT Edition Update 14 -DWG File Opening Time Follow up

Much like the previous blog, in this blog, you will find results of a comparative study conducted to analyze the file open time for a DWG file between MicroStation CONNECT Edition Update 13 and Update 14. We came up with enhancements in the previous update and narrowed down a finer scale for users to analyze the File Open time for a DWG File. The DWG File open Time has shown constructive improvement, where the machine has multiple processors, the performance of the .dwg file open time has drastically improved in Update 14.

The test results are assembled using different variables, based on multiple core processors. It was clearly observed that MicroStation Update 14 draws better results as compared to Update 13

The file opening time for a DWG file in Update 13 was trending at an average of 240 seconds and now with Update 14, it has come down to 60 seconds.

Following are the specifications that were used for the test.



Windows OS

Windows 10 Enterprise


Intel(R) Xeon(R) CPU E5-1660 v3 @ 3.00GHz, 3001 Mhz (Megahertz), 8 Core(s), 16 Logical Processor(s)


64 GB

Page File Size

9.50 GB

Graphic Card

NVIDIA GeForce GTX 980

We have made use of both MicroStation CONNECT Edition Update 13 and Update 14 respectively.


Chart Content: The chart below represents the various datasets used from multiple verticals showing the time required to open a DWG file in Update 13 and Update 14.

These tests have been conducted multiple times and the average loading time was considered to obtain the graph below. The datasets used for the tests are from different verticals which help in gauging the performance. The objective of this study is to help our users understand the difference in the .dwg file open time between MicroStation CONNECT Edition Update 13 and Update 14.


Graph Content:

  • X Axis: Dataset
  • Y Axis: Time (In Seconds)

The general perspective of this graph is to show the overlapping results between MicroStation CONNECT Edition Update 13 and Update 14. However, in the Building model dataset, the graph substantially increases in favor of Update 14 with an average of 8.5 seconds in contrast to 170 for the same.

These tests were performed specifically for time required to open a DWG File in MicroStation CONNECT Edition Update 13 and in Update 14. With improved changes in the current update, we have a lot more in store for the next Update.
