Ooops, yes, you are right ! I always test the TCP stack through a limited test of ApacheDS (and sometime I do the same with Databases) ! ;-] eh eh eh > > If the test makes a connection, then performs bind/search/unbind > (which > will disconnect), then the overwhelming proportion of the effort to > handle the load > goes in setting up and tearing down the TCP connection.

Which is kind of high... Ok, ok. Do not push this test too far. It's not realistic. It's just a kind of baby test (very very young ! It's just one cell, actually, and it will divide soon to two cells, then 4, then ...) Call it very premature ;) Nevertheless, I like those results ! Emmanuel
