ECO versus EJB versus 8I

Question

Hi,
I want to compare ECO upon OAS, EJB upon OAS and EJB in Oracle 8i (8.1.5).
For that, I wrote a little component which has 3 methods:
- send a string of 50 000 caracters
- open an Oracle Session via JDBC
- read 2 000 lines in the table travel (Hotel example)
The client is a Java application connected to the server via 16Mb.
Oas and O8i are on the same server (NT 4)
The results:
ECO sendString 206 ms openSession 224 ms readTravels 1154 ms
EJBOAS sendString 306 ms openSession 329 ms readTravels 3567 ms
EJB8i sendString 918 ms openSession 157 ms readTravels 3560 ms
The same but in Client/server 2 levels
Local sendString 78 ms openSession 562 ms readTravels 1485 ms
Conclusions?
ECO better than EJB (RMI is the reason perhaps?)
EJB8i not optimal even in reading databases?
Question for Oracle Team:
Now,I start a project built upon OAS and Oracle 8i and Java. EJB in OAS and 8i doesn't seem very mature, isn't? Have you benchmarks for comparaison beetwen ECO and EJB ? Can I expect better performances in next release? When ?
Thanks.

The double quotation marks strictly unnecessary ... unless you are dealing with objects that don't adhere to the standard naming convention.
So, if your table is called MYEMP then these three statements are the same...
SELECT * FROM myemp
SELECT * FROM MYEMP
SELECT * FROM "MYEMP"
/ But if someone has been ill-mannered enough to name the table using lower or CamelCase (which inself neccessitates the use of " in the CREATE statement) we must also reference it using double quotes...
SELECT * FROM "MyEmp"
