Some places where `FileInputStream` was being used didn't have `BufferedInputStream`. In many of the use cases, these files were being read 1 byte at a time. This causes excessive IO calls to read the file. By ensuring the `InputStream` is buffered, the IO calls are minimised, improving the performance of the driver.

This performance issue was noticed when a certificate file was on a network drive. It resulted in considerable network traffic.
