Undocumented TCP settings, IBM please help

In regards to my server performance problem

http://www-10.lotus.com/ldd/ndseforum.nsf/xpTopicThread.xsp?documentId=2C98A8A6601D58D88525818600376E80

I found a solution as described here

http://nevermind.dk/nevermind/blog.nsf/subject/ibm-domino-a-very-annoying-performance-issue-now-solved

 

The server had  TCPIP=TCP,0,15,0,,45088, in notes.ini and detaching was very very slow. Changing  this to TCPIP=TCP, 0, 15, 0,,32800 detaching gets very fast.

Documentation for 32800 value:

http://www-01.ibm.com/support/docview.wss?uid=swg21164925

This documentation only describes how to get 32800 value by combining encryption end compression.

But what are the other TCP port flags that gives the value 45088 ??

IBM please document what it is and why the value is used, thank you

 

(The value TCPIP=TCP,0,15,0,,45088, is set by the Admin client when enabling encryption and compression I believe. )

Not the answer - but found this add'l information

http://www.kalechi.com/doc/notesini.nsf/85255a87005060c585255a850068ca6f/8d0f57b937909eefc1256e9e0045eddb!OpenDocument

Configuration for a TCPIP port.

Examples: TCPIP1=TCP,0,15,0,,12288

TCPIP=TCP, 0, 15, 0 [,,x] <----------- This is the setup for your TCP Port
.......|...|..|... Application Data buffer size (0 is default which = 8000)
.......|...|..Placeholder not used by TCP
.......|...Placeholder not used by TCP
.......This is the port driver name

The last parameter x ([,,x] above) can be decoded as follows:
0 X 8000 Encryption is enabled
0 X 0020 Compression is requested
0 X 4000 driver is internal
0 X 2000 no-op
0 X 1000 always for V2 and V3
0 X 0002 set to log modem I/O
0 X 0004 set to enable RTS/CTS

Selection NOTES.INI parameter
Nothing TCPIP=TCP,0,15,0,,12288,
Compression only TCPIP=TCP,0,15,0,,12320,
Encryption only TCPIP=TCP,0,15,0,,45056,
Both TCPIP=TCP,0,15,0,,45088,

Good deal, Mark, it's plenty to get to the answer

These decimal numbers are actually binary flags.

450088 = 1011000000100000

Splitting em up yields:

x8000 + x2000 + x1000 + x20

... and your codes supply the definitions of each flag.
