IC47731 has to do with poor TSM server performance under mainframe
Linux, resulting from frequent use of the backtrace() function.

The APAR mentions poor performance on SLES 9 and RHEL 4, both of
which are based on the 2.6 Linux kernel. Does the same problem
occur with SLES 8, which is based on the 2.4 kernel?

The APAR states that fixing the problem 'gives TSM a big performance
boost'. Does anyone who has installled the fix have quantitative
information on how big 'big' is?
