Extremely slow encoding

[JanLeysen]

On my old laptop (Dell) I am using dBp 14.1 which works very good and encoded rapidly (a CD would take about 5-6 min on the average to rip to FLAC).
I have just installed dBp 14.2 on my new laptop which is at least as powerful as my "old". However on this laptop (Lenovo) dBp is painstakingly slow at encoding. The same CD may take up to an hour to rip (!).
It is NOT the "problem of Windows switching from DMA to PIO" (see other treads; I had this problem at one point on my old laptop).
Any suggestions? Could it be the new version of dBp? What could I check?

Re: Extremely slow encoding

What ripping method are you using? I suspect the quick rips on the old machines are because you were using Burst Mode. If the new one is set to Secure or Defective by Design, it'll take a lot longer.

I was also using secure.

Re: Extremely slow encoding

Try setting the codec as test conversion, and no dsp effects, rip one cd to get a base ripping speed.

Re: Extremely slow encoding

Here are the test results:

On my (old) Dell:
FLAC with DSP (HD HDCD, RG Replay Gain, Move Destination File): 7 min 42 sec
Ripping speed starts at x13 (first tracks) and increases gradually to x22
(Ripping Speed is set at “Maximum” in dBp)

On my (new) Lenovo:
With codec as test conversion and WITHOUT DSP: 8 min 15 sec
FLAC WITHOUT DSP: 8 min 15 sec
FLAC with DSP RP Replay Gain: 7 min 36 sec (like the Dell…)
FLAC with DSP HDCD: 18 min 20 sec (!!)
FLAC with DSP HDCD and RP ReplayGain: 23 min 40 sec (!!!)
Ripping speed starts at x6 (first tracks) and never exceeds x10
(Ripping Speed is set at “Maximum” in dBp)

There seems to be a conflict between the DSPs RP and HDCD (?)
What should I do?
Is it save to remove the DSP HDCD?
Is the slow ripping speed on the Lenovo “normal”?

Re: Extremely slow encoding

Remove the HDCD as it has to rip to a temp file, but it should only be slightly slower.

RP ReplayGain should not overly effect ripping time certainly not 3x slower. Try some bench marking software on your Lenovo to check against other PCs (both CPU + Memory + HDD speed).

Re: Extremely slow encoding

I did the benchmarking: PC has excellent speed.
Ripping speed is a disaster. Just took me 25 min to rip a CD to flac (same takes 5 min on my old PC).

Is it possible to download the previous version of dBp?

Re: Extremely slow encoding

The version of dbpoweramp should not make any difference....

What security software do you have on the new PC?

Re: Extremely slow encoding

I suggest you consider investigating into a different drive perhaps an external one. I reverted back to an older IDE drive I owned. I stumbled upon its specs in Spoon's Drive Accuracy List. Subsequently my rips were almost twice and definitely more accurate. Particularily, when some erroneous tracks required re-rips by dBp the older drive breezed through them compared with newer drive. Instead of hammering bad blocks, it pulled off the data quickly. I can post an extraction log of a particularly troublesome CD with which I tried both drives. In it you will see more accurate and quicker DAE.

I admit there might be other explanations for your slow performance but my solution is the most obvious and productive for troubleshooting.
