Performance Enhancements to the HSC FDDI
Driver
HP-UX 11i includes code that enhances the HSC FDDI driver. These
driver modifications increase performance of theFDDI link by up to 20%.
The performance enhancement was done by making the driver
MBLK-based, whereas previously it was MBUF-based. Other code-path
and function-call reductions have further improved performance and
scalability. These changes are not directly visible to the user and have no
effect on current documentation or support.
