With more than 1800 messages in the outbound queue cache misses went up:
Object Instance Counter Value
Physical Disk D: (TCOSS) Disk Writes/sec 103
Disk Write Bytes/sec 632,000
Disk Reads/sec 14.4
Disk Read Bytes/sec 187,000
%Disk Write Time 67
%Disk Read Time 6.3
TCOSS Cache Database Cache Misses/sec 0
Directory Cache Misses/sec 1.3
Document Cache Misses/sec 13.1
Database cache misses were about 2 per second at the beginning of the test and then decreased to zero,
independent of the outbound queue length, because all the configured 50,000 mail entries fit into the
database cache.
5.9.6 Test Results: TC/Web User Access Simulation
The “WAPT” load and stress testing tool was used to test simultaneous access by 50 web users. The 50
users did a number of pre-recorded operations (login, list inbox, open message from inbox etc.) without any
delay in between.
During this test the fax work flow as in “Test with 2-page messages and increased TCOSS cache” above
was also running, the outbound fax queue length was between 100 and 500 so the TCOSS cache worked
efficiently.

The increase in CPU usage is mostly caused by the IIS worker process “w3wp” which handles the web
server requests. TCOSS CPU usage also increases to 47% (on a scale from 0 to 400).
