I have a lot of models I deal with regularly that I will get from Vendors/Internet, change visually to what I need them to represent and then save them. Usually after that I never need to make adjustments anymore. I have one part that has an extremely high rebuild time. Again it probably could be modeled better to improve the time but I just don't have time to rebuild this file now.

I then took the file and saved it as STP file and then reloaded it into Solidworks Part and saved. It reduced the rebuild time drastically.

However the whole part is now imported, which isn't really a huge issue for me. The one question I have is what is the best way to go about this, I eventually end up with 2000-10000 unique files in my final assembly and if I have multiple parts with rebuild times of 22.64 seconds it takes forever to do anything. Is there a better way of reducing rebuild time rather than exporting into a stp and re-importing?
