    Well yeah that does look like it will mainly be L1 cache misses.

    10 cycles for an L1 cache miss does sound about reasonable, probably a little on the low side.

    A read from RAM is going to take of the order of 100s or may be even 1000s (Am too tired to attempt to do the maths right now ;)) of cycles so its still a huge win over that.
