Hi Amaete, pipelines were not originally designed to handle more than a hundred prospects, so it's important to optimize their performance. In the meantime, here are a few suggestions: remove prospects in the "Added" stage until you're ready to send them through the process, and remove those in the last/rejected stages who you don't intend to contact again for a while. When you remove someone from a pipeline, their history, comments, and files are retained, and if you add them back in the future, all the old data will return. However, deleting someone from the directory permanently erases all their data.
