1.6.4 vs 1.6.3 - disc read speed

[mike admin]

The disc access layer was updated in MakeMKV v1.6.4 . We did extensive testing on all 3 OSes and observed about 3x increase in disc read speed versus 1.6.3 . However, some users experienced a drop in disc read speed. This is the main topic to discuss the new IO code. Please reply with following information:

• Did it became faster or slower? How much?
• What OS are you using, and on what architecture (32 or 64 bit)
• For Windows, please indicate whether you have a 3rd party UDF driver or on the fly decryption software installed
• For Mac please indicate whether DASPI is turned on
• What drive do you use and how it is attached (internal or external)
• Did you test DVD or blu-ray disc

Generally, new version should be a little bit slower at start of each title but significantly faster overall. Make sure your voice is heard if this is not the case. The last version with old IO code, 1.6.3 may be downloaded at http://www.makemkv.com/download/old

I did notice an appreciable speed increase running .4 over .3, but unfortunately I have not had a completed rip with the latest version. The discs both moved quite quickly to roughly 35% completion, then failed (and I retried several times). Rolling back to .3 gave me successful rips of the same discs.

- Win7 64 Ultimate
- No UDF driver or additional decryption software installed or running
- LG GGC-H20L HDDVD/Blu combo drive, internal SATA
- Blu-ray discs "Extract" and "Invention of Lying" tested

Just upgraded to 1.6.4 and am having significant speed issues. DVD rips are taking 60-90 minutes.

Win XP Pro SP 3
No 3rd-party drivers or decryption software
Internal IDE HL-DT-ST DVD-RAM GH22NP20
DVD

Also, makemkvcon.exe memory usage is sky-rocketing, and the application will not exit cleanly.

Thanks.

1) Gradual speed increase over the course of a full disc Blu-ray backup results in an overall speed increase of approximately 25-30%

2) O/S is Windows Vista Home Premium 64 bit

3) No third party driver installed

4) Drive info: (Internal)
Manufacturer: HL-DT-ST
Product: BDDVDRW GGC-H20L

5) Tested with Blu-ray full disc backup

[cigamit]

1) Much Slower

• 1.6.3
  4.5-5.5X speed
  12:47 Elapsed Time

• 1.6.4
  1.5X-1.7X speed
  35:12 Elapsed Time

2) Windows XP 32 Bit

3) No UDF Driver

4) Source: Internal SATA (DVD_R-DL TSSTcorp DVD+-RW TS-H653B D300)

5) Tested with different DVDs, same result

Host OS: openSuSE 11.3, Linux 2.6.34.7-0.7-desktop (x86_64)

DVD Disc-1 (FF):
Duration: 1:45:24, Single title MKV Backup of 5290.8M (5,125,564,649b MKV)
- Data capacity: 7.48 Gb
- Disc type: DVD-ROM
- Disc size: 120mm
- Maximum read rate: 10.08 Mbps [1x]
- Number of layers: 2 (OTP)

Using Internal SATA drive: DVD+R-DL, TSSTcorp CDDVDW SH-S223Q SB03
MakeMKV 1.6.4 backup to MKV = 10.58min
MakeMKV 1.6.3 backup to MKV = 13.12min
SomeOther 8.0.7.3 backup to VTS = 13.09min

Using Internal IDE drive: DVD+R-DL, SONY DVD RW DRU-720A JY08 (same host)
MakeMKV 1.6.4 backup to MKV = 10.03min
MakeMKV 1.6.3 backup to MKV = 10.08min
SomeOther 8.0.7.3 backup to VTS = 10.02min

I noticed that sometimes MakeMKV's reported read rate was as high as 10x, then it might immediately drop to 4.5x. As these DVD discs are in pristine/original condition, my guess is that the change in reported read speeds is not related to the DVD disc's condition or even MakeMKV, but is really based upon the selected video-data's physical track location on the disc (the outer DVD tracks are read in at a higher rate [more data per revolution] at the given disc speed resulting in the "faster" read rates). Bottom-line; any reported/perceived speed/thru-put differences must be measured as the application's overall save/copy time for the selected title on a given DVD disc.

CPU utilization on 1.6.4 was usually between 14-8%, with stable memory utilization.

I'm happy with the 1.6.4 tweak, curious why it seems to only favor/improve the SATA based I/O...

4 is much faster for me.
Osx 10.6.6
2010mac mini
Seems about twice as fast for me

But some movies won't copy, 3 copies them fine

[crowfax]

Did it became faster or slower? How much?
Faster. Max read speed on blu-ray is now around 5x, previously max'd out at 3.8x

What OS are you using, and on what architecture (32 or 64 bit)
Ubuntu Linux 10.10 32-bit

For Windows, please indicate whether you have a 3rd party UDF driver or on the fly decryption software installed
N/A

For Mac please indicate whether DASPI is turned on
N/A

What drive do you use and how it is attached (internal or external)
Plextor PX-B310U 6X BD-ROM USB External (website)

Did you test DVD or blu-ray disc
Tested 2 Single layer BD's and 1 double layer BD.

New Version 0.4x
Old version 3.9x (keeps going up but a quarter of the way through it is at 3.9)

I am using Windows Home Server(32) with a UDF driver I think from an add in called "my movies"
I use an external usb drive Asus SBC-06D1S-U/DBLU

[wb4dwd]

SLOW Slow Slow.

I wondered what was wrong with my computer...
Then realized the software was different.

Experienceing about a 75% REDUCTION in speed.

Setup:
Windows XP PRO SP3 32 bit
Intel I7 in a Gigabyte MLB
4GB RAM
Internal 20x DVD-RW Liteon
Speeds before ranged from 4-8X
Now seeing 1-1.8
Looking at an hour plus to rip
a single regular DVD.

No UDF drivers installed by me.

[vdegas]

Slower speeds, PC hanging now during rips when it never has before upgrading.

Did it became faster or slower? How much? 50%+
What OS are you using, and on what architecture (32 or 64 bit) 64bit
What drive do you use and how it is attached (internal or external) internal
Did you test DVD or blu-ray disc both

[litlgi74]

Same here.... 1.6.4.... Sloooooow! Went back to 1.6.3.

Did it became faster or slower? much slower: 1.6.4 = .4x 1.6.3 = 7.3
What OS are you using, and on what architecture (32 or 64 bit): WHS... OSX seems to work fine on 1.6.4
What drive do you use and how it is attached (internal or external): LG UH10LS20 internal
For Windows, please indicate whether you have a 3rd party UDF driver or on the fly decryption software installed: thdudf.inf
Did you test DVD or blu-ray disc: both

I had previously used MediaCodeSpeedEdit to modify the firmware for my LG CH10LS20 to enable higher ripping speeds. After 1.6.4 was released i restored my original firmware so that i could see if the new version had overcome the speed limiting issues. Unfortunately, 1.6.4 with the original drive firmware is much slower than i had using a modified firmware and 1.6.4. With my modified firmware i could get between 4X and 6X. With the original firmware and 1.6.3 i hover between 2X and 3X.

Please, please, at least specify your OS.

rcork,

I have the exact same drives as you and had to apply original firmware with riplock in place to make 1.6.4 work reliably. I still get better rates than you though; 3-4.5X with 1.6.4 and unmodified 1.00-03 firmware.

I got the same issues with my LG HDDVD combo drive too; it seems the faster ripping of 1.6.4 upsets quite alot of drives, is it only LG and TSSTCorp that affected?
