Looks like Sun has been paying attention to the good features of Linux and
implementing them. I guess Sun decided that that game can be played both
directions. :)

- Can address 17.5 terabytes of memory, 9TB files
- Arithmetic computations get to use 64-bit registers and operations
- UFS logging (mount -o logging /dev/dsk/c0t0d0s0 /mnt)
- mount "noatime" support
- TCP performance enhancement with SACK, RFC 2018
- New crash dump features
- BIND 8.1.2
- Sendmail 8.9.1b
- improved poll(2) system call (used in many applications)
- increase in number of filedescriptors
- Full Unicode 2.1 support
- Better threading subsystem
- Kerberos V
- Lots of new CDE apps/improvements
- Netscape 4.05
- directory name lookup cache optimized and now dynamically allocated on demand (static before)
- significantly improved paging algorithim, not "on" by defaultadd the line: set priority_paging = 1 to /etc/system,
andreboot- Note, backported to 2.6 kernel patch
"-09"http://www.sun.com/sun-on-net/performance/priority_paging.htmlIMPORTANTNOTE: Ensure that data files do not have
theexecutablebit set. This can fool the VM into thinking that these are reallyexecutables, and will not engage priority
pagingon these files. - some new commands likeplimit(1): Set or get resource limits of a process by taking aprocess ID
(PID)as an argument (limit and ulimit only work with thecurrent process) pgrep(1): Find a process by name and print the
PIDpkill(1):Find a process by name and send it a signal specified onthe command line traceroute
Did I mention that "facls" (man setfacl) added with Solaris 2.5.1 are damn
usefull?
