The more packages you have on your Studio means the slower your Studio is likely to be, much like any other system or application with add-ons (Excel, Word, etc).
As @Nithin_P mentioned on one of your older posts, it is better to not have any redundant packages, as this will slow your Studio down. Stick to the packages you need to work with, and don’t add any unless you specifically need them.
The packages I normally use are as follows, and these are commonly default:
If you require any different packages, for example
UiPath.Word.Activities then you can install the package on your studio. However, if there is no use for the package, you may as well remove it from your Studio.
