| From: | | Victor Sokovin |
Hi Peter,
| | From what I've read in the link you sent and the knowledge base, it seems that the main benefit of adding the COP entries is that the
parsing engines on the new nodes will be used to handle logons and requests from existing sessions. The AMPs on the new nodes would be used
either way, so the performance improvement is through workload distribution among PEs. | |
I am more with the earlier response: the more doors (COP) to knock on, the faster a connection can be established. Once in, it does not matter
any more through which door we entered.
If only a subset of nodes are handling the connections, the logon management is unbalanced and the new nodes do less than they should.
Regards,
Victor
