CDDA extract very slow

[tsh]

Not sure where the problem is. I have a new sata dvd writer from LG, and it won't extract digital audio at much more than 1x, or maybe 3x with -Z. I can write to it OK, so I'm guessing DMA is working properly.

Using cdda library version: 10.2
Using paranoia library version: 10.2
Checking /dev/cdrom for cdrom...
Testing /dev/cdrom for SCSI/MMC interface
SG_IO device: /dev/sr0

CDROM model sensed sensed: HL-DT-ST DVDRAM GH22NS50 TN02


Checking for SCSI emulation...
Drive is ATAPI (using SG_IO host adaptor emulation)

Checking for MMC style command set...
Drive is MMC style
DMA scatter/gather table entries: 1
table entry size: 131072 bytes
maximum theoretical transfer: 55 sectors
Setting default read size to 27 sectors (63504 bytes).

Verifying CDDA command set...
Expected command set reads OK.

Attempting to set cdrom to full speed...
drive returned OK.

=================== Checking drive cache/timing behavior ===================

Seek/read timing:
[56:52.10]: 73ms seek, 1.55ms/sec read [8.6x]
[50:00.00]: 62ms seek, 1.66ms/sec read [8.0x]
[40:00.00]: 96ms seek, 1.80ms/sec read [7.4x]
[30:00.00]: 84ms seek, 1.99ms/sec read [6.7x]
[20:00.00]: 85ms seek, 2.27ms/sec read [5.9x]
[10:00.00]: 117ms seek, 2.69ms/sec read [5.0x]
[00:00.00]: 144ms seek, 3.47ms/sec read [3.8x]

Analyzing cache behavior...
Approximate random access cache size: 16 sector(s)
Drive cache tests as contiguous
Drive readahead past read cursor: 234 sector(s)
Cache tail cursor tied to read cursor
Cache tail granularity: 1 sector(s)
Cache read speed: 0.13ms/sector [101x]
Access speed after backseek: 3.42ms/sector [3x]
Backseek flushes the cache as expected

Drive tests OK with Paranoia.

Any success? I've got a similar (same) drive:

ATAPI CD-ROM, with removable media
Model Number: HL-DT-ST DVDRAM GH22NS50
Serial Number: K00998K1011
Firmware Revision: TN01
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6

I find that a CD I can rip in about 5 minutes on my older PATA Sony drive takes 4 to 5 times a long on the newer one. I've sort of given up on searching for answers on this ... for the cost of a drive I may just grab another Sony.

But, before I do ... I'm sure it's a "little thing" and really would like to resolve it.
