The test run was done with messages of 2 pages, both average image pages resulting from the input PDF

attachment. The outbound messages were put into TCOSS by four TC/LINK-XML instances, 2 on the

primary and 2 on the secondary master. Outbound message size in TCOSS was about 150,000 bytes (PDF

attachments plus TCI alternative). The size of the received messages was about 135,000 bytes.

The message throughput was 150 messages per minute: 75 outbound and 75 inbound (received fax)

messages. This gives a fax line usage of 60 seconds per message, including the idle time between

message transmissions. The duration of the transmission, as seen in the outbox, was 46 ..47 seconds.

The number of messages put into TCOSS by the links was a bit larger than the number processed by the

fax lines, so outbound message were queuing up in TCOSS at a rate of about 700 per hour.

The TCOSS cache worked very well up to about 700 queued outbound messages, and was less efficient

with more queued outbound messages. The performance counter values below are taken from the phase

with more queued messages because this situation persisted during most of the test run.

The following values were measured with the Performance Monitor (on the primary system):
