NTS defines buffer pools for allocating all resource records, session records, and trace data kept in virtual storage. No storage is allocated until NTS begins SAW processing. Storage allocation and NTS processing are carefully managed to produce low system overheads and paging rates. All NTS buffers are located above the 16MB line.
It is possible to retain all session information and to trace all session activity on most installations, with little or no loss of performance. This does, of course, depend on the extent of system resource consumption during network operation.
