Ok here is my data:
I only used one test. It's impressive enough :)

Old Packages:

./openssl engine
(dynamic) Dynamic engine loading support
(pkcs11) PKCS #11 engine support


./openssl speed -evp aes-128-cbc

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192
bytes
aes-128-cbc      85871.89k    92796.71k    98383.53k   100017.49k
100256.43k


just for test if that helps:
 ./openssl speed -engine pkcs11 -evp aes-128-cbc
engine "pkcs11" set.

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192
bytes
aes-128-cbc      86177.13k    94786.86k    99174.31k   101733.38k
100578.65k


New packages:

./openssl engine
(t4) SPARC T4 engine support
(dynamic) Dynamic engine loading support
(pkcs11) PKCS #11 engine support



 ./openssl speed -evp aes-128-cbc
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192
bytes
aes-128-cbc     413248.17k   784163.48k  1008435.11k  1061075.63k
1103601.66k

./openssl speed -engine t4 -evp aes-128-cbc
engine "t4" set.

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192
bytes
aes-128-cbc     410416.72k   781939.48k   999663.45k  1055936.51k
1103432.36k


So same here T4 engine is enabled by default. Well according to this post:
https://blogs.oracle.com/darren/entry/howto_turn_off_sparc_t4

You can't turn it off anyway.

it seems to work :)
