Could well be a good reason why you only have 73% Have you just rebooted the system?

700,000 is a very high number esp on 32bit windows. The larger this number the less memory other parts of the system will get as you have taken it all for the program buffer.

What's the rest of your parameters set to?

How have you derived the value in the first place?

which Windows Release (32/64 Bit)

which SAP Release ?

[markus_doehr2]

if you´re on 32bit Windows I´d be carefull raising the buffer too high.

I configure the buffer 1.500.000 on Unicode systems and about 950.000 on non-unicode systems (depending on the application).
