Introduction to the jerasure library interface and Performance …

WebJerasure converts the matrix to a schedule which eliminates all of the matrix traversal and entry checking during encoding. Cleversafe's poor performance relative to Luby can most likely be attributed to the Java implementation and the fact that the packet size is hard coded to be very small (since Cleversafe routinely distributes strips in units of 1K). WebJerasure inits some global variables on init. We need to free them, or we'll leak memory.
