Hi all
Small intrusion in the Threads discussion
1) don' t forget other OS .. the linux is not the only one (for now :-)
)
For example check the performance under Solaris
http://www2.linuxjournal.com/lj-issues/issue70/3184.html
2) unfortunatly some platforms that had no threads (but is a few) or an
incompatible threads library (the major .. )
On the informix doc i read :
To most effectively utilize system resources, a configurable pool of
database server processes called virtual
processors schedule and manage
user requests across multiple CPUs and disks.
User requests are
represented by lightweight mechanisms called
threads. Each thread
consists of a single sequential flow of control
that represents part of a
discrete task within a database server process.
For example, a
processing-intensive request such as a
multi-table join can be divided into
multiple database threads (subtasks) and spread
across all the available
virtual processors in the system.
Could be intresting:
One process for connection client ,but composed with many threads
(similar to apache 2.0)
- No crash all the system
- Better performance in sql execution (i hope)
I think will be the way for the future (Postgresql 8.0 ? ) , i know is
not simple
