The test was performed on a single machine with an 8 CPU core processing power, and in a cluster configuration with a combined 16 CPU core processing power. B2B Data Exchange sent documents with different file sizes to PowerCenter, which processed the documents by value with the X12 Parser transformation.

For the single machine, PowerCenter was configured to use 32 partitions. For the machine cluster, each PowerCenter installation was configured to use 16 partitions, with a total of 32 partitions.

The following table describes the performance benchmark test results:

File Size	Number of Machines	Events per Second	PowerCenter Partitions
2KB	1	385	32 partitions
2KB	2	500	2 x 16 partitions
6.5KB	1	189	32 partitions
6.5KB	2	367	2 x 16 partitions
16KB	1	98	32 partitions
16KB	2	187	2 x 16 partitions

The table illustrates that the machines reached maximum throughput when both machines in a cluster use 32 PowerCenter partitions to process a 2K file size document with no processing errors.
