Submitter confirms it's been the ISP clock setting.

Well, you were right, the isp clock was set to 953.29us. Thanks for the pointer.

It's always advisable to run the most recent firmware revision.
Alas, that requires a machine running AVR Studio in order to
upgrade the firmware.

Anyway, did you remember to set the ISP clock to a sane value?
I've also seen AVRISP mkII devices that ship with a really
sloooow default setting. As the setting is remembered in
EEPROM, all it takes is to once connect using terminal mode,
and issue a command like "sck 5".

When programming flash memory it takes 4.18 seconds per 64 byte packet.

Attached is the output from a verbose writing.

What firmware revisions are you guys using for the mkII?
