- Does anyone have any clues as to why we experience the following problem
- using sockets on AIX 3.2.1 ?
-
- We send a message, consisting of a header and data in two parts onto a
- socket. The receiver receives the message in two parts. The header
- is always 64 bytes long. When the data portion is 1451 bytes long (or less)
- the response time is more than when the data portion is 1452 bytes long; 'more'
- means consistently longer by about .2 of a second. The same thing happens
- for data portions 1453-2903 bytes long, but data portions 2904 bytes and
- longer have good response times. We are running over Token Ring and the
- maximum IP packet size for TCP/IP is 1492 bytes (is this a clue ?).
-
- When we combine the header and the data in one message, response times are
- consistent over all message sizes.
-
- Any ideas would be welcome.
