It took a lot of time to get GUI working - SNMP needs non-trivial configuration whether you are using bundled master agent or one which comes with Informix. GUI however is full of ....ehhh .. peculiarities. Performance wise : sample script execution time - 20 sec without replication. Then CDR gets turned on in simpliest of scenarios , execution time 33-40 seconds. 50-100 % degradation on replicated server, in other words. I have not done too much work on API, but anyway I had to reinitialise the instance twice in two weeks as I managed to screw it so badly playing with th CDR. Again, it was testing environment. Personally, as it is in 7.22 I would not go for it in more or less serious production env. It was very first release of CDR, I hope next one will be cleaner and crispier. Cheers Ilya
