For the past few months we have all heard all the talk about the performance boost C3D 2011 will have running as a 64 bit software. So today I decided to run performance tests with the new 64 bit C3D 2011 and the 32 bit C3D 2010. The test was to see how long each version would take to save a drawing with 3 large shape files. I map connected in a shape file for all the streets of the Town of Flower Mound,Texas. In addition, I also added the shape files for all the subdivisions and parcels. Then I exported the drawing as a dwg file. What this basically does is converts the shape data into basic polylines and hatches. I repeated the same process in C3D 2010. On top of that, I ran the same steps twice to get an average time. I posted my results below with information on how memory each program was using.
CIVIL 3D 2010 (32 bit): 6 min. 53 sec.
Memory Usage = 461 MB
Dwg File Size: 11.675 MB
CIVIL 3D 2011 (64 bit): 1 min 2 sec
Memory Usage = 436 MB
Dwg File Size: 11.667 MB
As you can see, C3D 2011 running as a 64 bit software uses slightly less CPU usage and memory. I also ran a test on startup time when opening each version. C3D 2010 took 7.9 seconds while C3D 2011 took 14.2 seconds. So that was interesting results. Anyways, just remember that the software is only as good as the person using it, so adequate training is a most. In conclusion, the new 64 bit C3D 2011 will increase your productivity and performance.
For those using dual core or quad core processors you can use the WHIPTHREAD command to improve performance.. What this does is controls whether to use an additional processor to improve the speed of operations such as ZOOM that redraw or regenerate the drawing. This can come in handy when you have large surface drawings with aerials. I just happen to come across this in one of the blogs website I follow. (Thanks Michael)
