Impressive Stephen! Would you have some details on cost per transaction and transactions processed per second? I am sure a number of IT managers out there would like some figures.
Whilst I suspect transactions per second may not be that different to RDBMSs, I am sure the cost would outshine the RDBMSs. I am also curious if the transactions were simple or complex transactions. Many transaction tests are done on a simple process as reading a row and doing a simple update. If they did the test where a complex calculation like some complex tax calculation had to be done as part of the update, where they had to read multiple cross reference files and update multiple files as part of the transaction. I suspect that there would be an exponential decline in RDBM TPS. The longer a record is locked in an RDBMS the greater the problems they have. They have in the past suffered performance issues in locking a single row and tend lock a group of records, so one can start imagining the issues with complex transaction in a high transaction load.
