RandomAccessFile.writeBytes(String) takes a string out writes it out in
bytes. What it neglects to say is it will write each byte out one-by-one.
This caused a performance problem on our machine. Its better to generate
your own byte array from string and then use RandomAccessFile.write(bytebuffer)

Some example truss output

23173:	read(8, "CAFEBABE\003\0 -\094\b\0".., 3203)	= 3203
23173:	brk(0x001749E8)					= 0
23173:	brk(0x001769E8)					= 0
23173:	write(17, " R", 1)				= 1
23173:	write(17, " e", 1)				= 1
23173:	write(17, " p", 1)				= 1
23173:	write(17, " l", 1)				= 1
23173:	write(17, " i", 1)				= 1
23173:	write(17, " e", 1)				= 1
23173:	write(17, " d", 1)				= 1
23173:	write(17, " :", 1)				= 1
23173:	write(17, "  ", 1)				= 1

N/A

This method has been improved by buffering the bytes to be written and making a single call to the underlying write method.

The same technique has also been applied to writeChars(String).
