I made the same experience now with PG 8.01, FC3 and 512MB memory. The previous
was PG 7.4.6, FC2 and 1GB.

The difference in performance between kernels 2.6.9-1.724 and 2.6.10-1.766 is
still huge.

I notice that in 2.6.10 the function accesses the disk much more.

Does anyone know what changes from 2.6.9 to 2.6.10 could cause this drop in
performance?

Regards, Clodoaldo Pinto
