MongoDB's cursor.skip() method is convenient for pagination but has a significant performance caveat: it iterates over documents from the beginning of the collection or index to reach the offset, making it increasingly slow and CPU-intensive as the page number grows. For large result sets, skip() can even become IO-bound. However, for small result sets, skip() performs well and is a reasonable choice. The key takeaway is to understand your dataset size and use case before deciding between skip/limit-based pagination and cursor-based alternatives.
