Hi, depends on what you consider wrong. Response time is definitely wrong. The system is, however, working. The system has on some occcasions, for the last two weeks, received messages at a rate that is faster than the system can handle. This is partly due to the fact that a number of huge messages (containing in the order of 10^4 objects) have been received and they request updates of objects of which there are a big number in the database. The current software hits severe scalability problems when this happens. We have during the last days, devoted a lot of attention to solving these problems by specifically hacking the software to optimize this type of updates. We have tuned the system parameters to the limit. We are currently in the process of trying out an update to the disk system (which to add to all of the above, has suffered an unusual amount of physical problems). We have also contacted the senders of the updates to try to have the messages split and give a chance to everyone else. We are looking at a front end for the database that will do some kind of batch queue handling enabling control over how resources are distributed to users, so that no single user can hog the machine. Also, this is impacting the efforts of the reimplementation project which is the ultimate solution for this problem. Hope this gives you a bit of an overview of the situation. I apologize for the incovenience this is generating for everyone but I assure you, we are doing our best to get this thing to work as fast as possible.
