There has been a discussion on the general list about this area. One of the members produced a test case for demonstrating rapid size increase.
I decided to see if I could induce similar behaviour with a more (seemingly) benign example. I tried this : 1) Create a table and load 100000 rows (with a primary key) 2) Run several threads update 1 row and commit (loop continously with a rest every 100 updates or so) 3) Run 1 thread that (lazy) vacuums (every 3 minutes or so) I ran 10 threads in 2) and saw my database grow from the initial size of 150M by about 1G per hour (I stopped my test after 5 hours @ 4.5G). The table concerned uses a large text field... it might be instructive to see if this is central to producing this growth (I will see if a more conventional table design can exhibit this behaviour if anyone is keen to know). For those interested the test case I used can be found here : http://homepages.slingshot.co.nz/~markir/tar/test/spin.tar.gz regards Mark ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
