the number of blocks allocated and read in a "chunk" is set by the disks cluste
factor (set to 4 for 2K basic units) and the RMS multiblock counts that 
determine how many blocks are read ahead/written behind when another I/O is
called for.  If Eunice is bypassing this entirely without doing the same itself
that could explain some performance problems.  In general VMS I/O speeds are
low compared to commerical systems like IBMs but reasonable compared to other
supermini operating systems.
