Hopefully some feedback is coming to my questions. 1) Did somebody a compile with the Intel ICC inclusive performance logging 2) Is there a hint where to find in the source the REGEX module and is there any connection to inheritance of table.(module???). 3) Is there a short description for shared memory use in PostgreSQL Thanks in advance Gottfried

The 7.4 development branch can be compiled with icc, earlier versions not without extra hacking. Some people have reported slight performance improvements, but in general PostgreSQL is I/O bound, so it shouldn't matter much. Others have also reported that binaries generated by icc corrupt the database or don't start at all. See the archives for details. My opinion is that it's not really worth the trouble. > 2) Is there a hint where to find in the source the REGEX module src/backend/regexp > and is there any connection to inheritance of table.(module ???). No. > 3) Is there a short description for shared memory use in PostgreSQL You can find some small hints at http://www.postgresql.org/docs/7.3/static/kernel-resources.html#SYSVIPC but there isn't really any developer-level documentation for that. -- Peter Eisentraut peter_e@gmx.net
