Hi

Sorry I never noticed the reference to IB_Pump before.

Geoff is correct. This is actually a FB 1.5 (<=) issue that is mostly
resolved in FB 2. The issue appears on Multi CPU / Core cpus with
SuperServer. We had a DB that took 45mins to pump, putting it on a dual
core machine pushed this out to 1.5 days. I think setting the CPU
Affinity fixed this issue. I would guess that the Vista machine is also
a new Dual / Quad core cpu.
