Programming Max10 with .pof is very slow

Hi,

I´m wondering about long programming times, when I program my 10M08SCE144.

It takes up to 4 Minutes.

Is this normal?

I´m already using a compressed .pof file.

I´m using the original Altera USB-Blaster.

Is there any way, to speed up programming process?

I can´t find anything about that topic, except the advice, to compress the .pof file.
