EAC and Lite-On LTR-48246S

I was trying to understand why the speed of extraction varies so much with the same settings and even with the same disc with my Lite-On 48246S.
I have "Drive Caches Audio Data" and "Drive is capable of retrieving C2 information" set and I use ASPI interface that comes with Nero. Sometimes the extraction (not the encoding) speed on average is at 15X whereas sometimes is at 3X. My problem is exactly this : The first track starts extraction around 3X and reaches to around 8X then the encoding starts, when the encoding process ends and extraction of second track starts it crawls around 3X for the rest of the extraction. If I restart EAC and do the same thing again, then the extraction speed of the first track doesn't change but *sometimes* the second track starts at around 7X and reaches to around 15X and from that point on I get around 15X extraction speed for the rest of the extraction for all tracks. I don't understand what happens in each case but it happens with the same CD so I can't say some CD has possibly more errors either.  Do you have an idea?

There was a discussion about something like this earlier on the boards here somewhere, but I'm too lazy to find the thread.

What it boils down to is that if you start the ripping process while the drive is spinned up (after like F4 or alt+o), then the extraction process is fast.  If you wait until the drive spins down, then the extraction process is slow and never speeds back up properly.

Hmm, that's what I thought so, thus set the "Spin Up drive before extraction" but it didn't help. What made the difference is Drive Options -> Offset Speed -> Speed Selection -> 40X (instead of Actual)  + Allow speed reduction during extraction. Now for some reason I get the same speed during extraction every time which is around 10X.

BTW when do you press F4 or Alt+O?

I press F4 to detect gaps and alt+o to create a cue sheet.  I do this right before I rip the cd.

BTW, F4 and Alt+O are just examples.

Even if you do nothing, and just start extraction right after entering the disk, you'll have a fast extraction

But isn't this a bug in EAC then?
