Quad Core Processors
I am about to upgrade my media PC to include an AMD Quad core processor. Is E-jukebox able to identify and utelise more than 1 core at a time?

Never mind. Windows seems to manage to thread the cores together. no probs.

Righto, sorry to bring this up again, but although Windows seems to manage the quad cores ok, E-Jukebox only seems to be able to fully utelise one
core.
anyone know why?

Sorry, should have said that I notice this when I am adding a lot of songs at a time.

Try this...move the scrollwheel back and forth real quick over shelf3d and see if it goes over 1 core of cpu usage. I believe windows will split the
cpu load over the 4 cores evenly unless you set the affinity in task manager. I don't think eJukebox will ever need to consume all of your cpu power
at the same time because the cpus still need to ultimately wait for responses from the hard drive.

Cheers Audiosoft, but I don't have the shelf 3D in my EJ lite version now ( :-(
What it is, I was moving music from an old hard drive onto my new set up (around 3000 songs) and while it was adding them to the EJ Database, it kind
of hung for a bit, then added them quite slowly. When I checked out the CPU usage, it showed one core maxed out and the others pretty much sitting
idle. When I looked at the processes it showed EJ using 24-25% (equates to 1 core) of the total available.

thanks for the report i will look into this more. btw are you on 64bit windows?
RE: but I don't have the shelf 3D in my EJ lite version now ( :-(
Why not? You can still use shelf3d with Lite (just not the shelf3d options and fullscreen) if you have 5 beta.

nah, just 32 bit. I used a trial of the 64 bit and I couldn;t get all the drivers i needed, so I binned it! I might try it again at some point in
the future though
As for the shelf 3d, I didn't realise it was only the full screen that was unavailable, I have just left it on the carousel. I will give that a go
when I get home.

I also experience something similar each time I start to add new songs to eJukebox, my PC hangs during about 8 or 10 minutes -I think it is making a
memory swapping because of the hard drive high activity- then after this long hanging time it adds the new songs at a normal speed.
The more annoying thing is it also hangs during 10 minutes when I add only one song or two songs or a cover using the song editor! Note that I have a
quite large database, Windows Vista, Dual core, but only 1Gb RAM.
Audiosoft, do you think that in my case the database update process would make good use of some additional RAM? I mean if that could prevent these 10
minutes of freezing?
Note that my other programs never freeze my PC, even if I edit a lot of large images in Photoshop.
Thanks.

Pirk and Well_Jaggy please give beta 16 a try and let me know if it gets rid of the delays for you when adding songs.

Audiosoft,
Wow!! Excellent work!
I've just added 4 new albums with covers to eJukebox using your beta 16: It added them in about 1 minute only! All is quite FAST now.. 
I don't know what you have changed or fixed? but it works good for me with my very large collection and only 1Gb RAM on Vista. 
Thanks a lot.

no worries. Actually got all my songs loaded now, but I will remove a few albums and give it a go again.
Also, Shelf 3d is available in place of the carousel as you said! Cheers!

I am going to do a big test on this tonight. I will download the trial version and install onto my new Vista partition and add my 28k+ songs. I will
let you know how long it takes.

after an hour, its slowed down and has only reached a total of 7,700. Its kind of hanging on every song now and seems to be taking around 15 seconds
for each song.

Well_Jaggy was that with 5 beta 17 or 4.90?
Make sure to use the 5 beta 16 or later ejukebox.exe for the speed improvement.

Its Beta 17.
I checked the progress when I got up this morning, and at 7:20 am (UK time) 14 and a half hours later it had added 19911 songs. Hopefully it will
have finished by the time I get home from work. which will be about 5:30 tonight.

just in from work and checked this. looks like the application has totally hung as it hasn't moved on from 19911 and is not responding. I have now
gone to the add new music section and started adding the rest of the songs now. PC still runnig ok, just EJ that stopped.

The last of the songs finished updating around 40 mins ago, so that was 9000 songs in around 3 hours.
Don't know why it slowed down then stopped before though.

hmm what about antivirus software? If you have antivirus make sure it is not scanning the eJukebox database and slowing drive access during setup.

0.09 Second / Song
In order to test the eJukebox import files speed, I just tried to build a new database from another eJukebox install (v5 beta 17).
Verdict: 0.09 second / song. Which means a average of only one second for each album, cover included!!
I think it's a respectable performance! In particular because this import speed never slow down during the hour taken to scan all my files.
Nice work Audiosoft!

Well_Jaggy, The import took 65 min! Take your calculator please.. 
Otherwise during the import eJukebox was running almost alone. I think only IE was open at the same time, displaying a few web pages.. I've not
turned off my antivirus (AVG). Vista 32bits, "Small" Dual Core, 1Gb RAM

just to make sure I worked that out right, 65 mins*60 (seconds) = 3900 seconds
.09 seconds per song
so
total time taken devided by time per song -
3900*.09 = 43,333 songs?
Thats a lot!

You are right, that's too much in fact.. but eJukebox digests good! It's just a shame that my PC becomes VERY slow (90% freezed) because of eJukebox
each time I close the program: Endless database compacting................. It's the ultimate eJukebox annoyance!
Audiosoft, maybe could you speed up the "famous" database compacting too? Is it really necessary to do that??

Pirk,
Give beta 18 a try it is under Latest Updates.
See the end of the beta 18 updates log for new ejukebox.ini options to disable shutdown compacting.

Audiosoft,
Great! That's a radical option, but 100% efficient!!  I think I will let this option always checked.. Unless it exists any
drawback I'm not aware of:
-What is the concrete effect on the database of the compacting process at each shutdown?
-Maybe it is necessary to compact the database at least once after adding new songs??
-Is it possible that eJukebox becomes less efficient on the long run, or even damage my mp3s(!?) if I never or rarely compact the database?
Thanks a lot.
