> File uploads using the Trinidad File Upload Framework are very slow with uploads typically taking several minutes for files on the order of 100MB. It is substantially slower than FTPing an equivalent file.
> After profiling the application, most of the sloweness is from inefficiencies in MultipartFormHandler.java.
> After making a few changes to the method _readline() and also using a BufferedInputStream, the performance was doubled.
