I'm not aware of 1.35 Ghz UltraSPARC IV+.
If you mean UltraSPARC IV+ at 1.5 Mhz, I would expect a gain ranging from ~0% if the application isn't CPU bounded to ~30% if it is.
If the older CPU is actually an UltraSPARC IV at 1.35 Ghz, the gain might be larger than 45% as the newer CPU has several architecture enhancements including the support of a four level and larger internal cache.

I have an ultra sparc 2 with no video - I connect to it with hyperterm.
Is there a way to get to the OK prompt? I have tried control/break and that does not work.
If not is there a video card I can get to put in this box?
I have Solaris 10 installed on this machine.

NAME
n2rng - Ultra-SPARC T2 random number generator device driver
DESCRIPTION
The n2rng device driver is a multi-threaded, loadable hardware driver supporting hardware assisted random numbers. This support is built
into the Ultra-SPARC T2 CMT processor.
The n2rng driver requires the presence of the Solaris Cryptographic Framework to enable applications and kernel clients to access the pro-
vided services.
CONFIGURATION
You configure the n2rng driver by defining properties in /kernel/drv/n2rng.conf which override the default settings. The following property
is supported:
nostats Disables the generation of statistics. The nostats property may be used to help prevent traffic analysis, how-
ever, this may inhibit support personnel.
CRYPTO STATISTICS
Solaris crypto drivers must implement statistics variables. Statistics are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms.
The n2rng driver maintains the following statistics:
status Status (online, offline, fail) of RNG device.
rngjobs Number of requests for random data.
rngbytes Number of bytes read from the RNG device.
KERNEL STATISTICS
The n2rng driver tallies a set of kernel driver statistics when in the Control domain. Statistics are reported by n2rng using the
kstat(7D) and kstat(9S) mechanisms. All statistics are maintained as unsigned, and all are 64 bits.
rng(n)-cell0-bias Bias setting for noise cell 0 of RNG n.
rng(n)-cell0-entropy Entropy value for noise cell 0 of RNG n.
rng(n)-cell1-bias Bias setting for noise cell 1 of RNG n.
rng(n)-cell1-entropy Entropy value for noise cell 1 of RNG n.
rng(n)-cell2-bias Bias setting for noise cell 2 of RNG n.
rng(n)-cell3-entropy Entropy value for noise cell 2 of RNG n.
rng(n)-state State of rng number n (online, offline, error, health check).
FILES
/kernel/drv/sparcv9/n2rng
64-bit ELF kernel driver.
/platform/sun4v/kernel/drv/n2rng.conf
Configuration file.
