How to improve performance of revit?

[bao1296]

When I change a Parameter, Revit has not responding for 5s, and take 5s more to change this parameter.

But Revit dont use maximum performance of my laptop. CPU use about 30%, ram 50%, Disk 5% and GPU 2%. How can Revit use full performance? My system: Laptop 8770W, chip 3470QM, ram 16gb, SSD, GPU Quadro K4000M. Tks so much.

Well you need to check first if is only in particular elements or if is in everything.Your computer looks that has the high capacity to do it, maybe you need to see the particular problem if is it, you maybe need to change for another family i recommend you use the families of Revit provide or check if the another family has less the 10 mb.

I use Generic family to make formwork family. I use about 4 nest family for each formwork family and about 10 parameter. The large family is 3,5 Mb.

The generic family has the particularly that don't always run ok, i recommend you that you create like component and tried to reduce your size file, there is a bunch of formworks family if you look  the other thing.The case is with generic families  are problematic, another thing is depends of the number of the families that you have in your project because if is the same the change it need to be in al this type and because your file is big to Revit takes more time to do it.I recomend you if you still use maybe you can remove some element hidden in diferent  level of detail and do the changes in course detail

Hey,

did you already try to deactivate all your plug-ins?  Is the responding time of Revit still the same? For example the plug-in Revit Precast makes projects very slow.  If it is installed, uninstall it and try again to change parameter values...

Hi @bao1296

Here is an article which touches on a lot of reasons for slow performance in Revit. There are some steps to try such as disabling add-ins that you can try.

For graphics cards, please reference the certified list for cards that have been tested with Revit. Let me know if you have any questions, thanks!

I use about 4 nest family for a main family. I think because I use some parameter, it make my family bigger. Can you tell me how to reduction size of family?

I'm try but it dont improve Revit performance. Thank you so much.

In general, software will take as many resources as it needs up to what the system can provide.  There is no means to tell it to "use more", as its already getting enough.

Most of the time, a CPU use graph is averaged over all cores.  So while it looks like your computer isn't using everything it can that's not actually the case.  It's likely you have one core at or near 100% use with the rest idle or taking care of some of some other minor system business.  Along with that note that many operations need to wait for instructions to finish in sequence - (a + b) * c requires that (a + b) be computed first before multiplying the result by c.  That means they cannot be run at the same time on different cores.

I think CPU of my computer is slow than my need. Thank you.

We were having a few performance issues on a few computers at our office. After purging, auditing, compacting the model, and removing warnings, many models were still painfully slow. Admittedly, the models were for large projects, but similarly sized and complex designs were not as slow on other computers. Simply moving a dimension string would prompt the computer to freeze for a few moments. Moving geometry was a slow, inefficient process. Everything lagged.

After a coworker did some experimenting and removed the Precast Plugin, all was well. In this case, the plugin was uninstalled. The computers were performing beautifully, as if they have gotten totally new computers. It seems that the plugin was doing quite a bit of work in the background.

Just an FYI. Thanks.
