Performance of Aurora ORB inside ORACLE.

Hello all

We were comparing performance of simple ping request on the Aurora on Oracle 8i Release 2, Oracle 8i Release 1, and on Inprise Visibroker 3.4 (Aurora is ORB that lives in Oracle kernel, in JServer, since first release of Oracle 8i, Aurora is derived from Visibroker 3.2, then 3.4)

Ping request was of several types, and was performed in simple loop:

CORBA ping request: call of "void doNothing()" located on server, JDBC ping request: call of "BEGIN NULL; END;" using JDBC thin driver v 8.1.6

Hardware: client is P-III 450 MHz, server is Sun Ultra 450 with 400(?) MHz.
Server multi-procesors weren't playing important role because only 1 processor was used during the test (sar output)

Results:

VISIBROKER:		~ 260 pings/second
JDBC:			~ 320 pings/second
AURORA R2:		~ 70 pings/second
AURORA R1, P-II 330:	~ 30 pings/second

I wonder why Aurora is so slow? Is it supposed to be slow? Go into the sess_sh, type "ls". See the items appearing one by one, slowly. Is it OK?

Anybody who played with this and achieved positive results comparable with two first options, please answer.
