Thank you for the update, Stan. Please also consider opening an issue
report detailing the specifics at Github (
https://github.com/ElvishArtisan/rivendell/issues) -- that way, itwon't get 
lost in the shuffle. 

Cheers!

Hi Fred

Thank you for the clarification, so all the improvements should be 
already implemented in the version I am testing with 2.19.3. As Cliff 
suggested I did try a modern PC with a very fast processor and lots of 
RAM, it did reduce the time taken by 50 minutes ( it previously took 2 
hours for 24 hrs of music) It still appears to be a long time 
considering the low complexity of the set up...


Thanks

Stan

The optimizations were part of the final batch of improvements
submitted by Alban Peigner before Tryphon ceased operations. They first
appeared in v2.12.0, and improved music scheduler performance when
generating logs by an order of magnitude or more. Thus, an update to
the current stable version (v2.19.3) should cure the OP's reported
bottleneck.

Cheers!

Re: [RDD] Scheduler codes time taken

2019-03-19 Thread Stan Fotinos

Hi Rich

Just the one group and one scheduler code and 20 tracks per hour. I have 
simplified the clocks just to see if it makes a difference, the only 
thing that does is if I only us groups and no codes at all.


It appears from the responses that some are able to create logs with 
scheduler codes reasonable fast but I'm just wondering if it has more to 
do with hardware or the software side of things. I'll be testing on a 
faster system at the end of the week and I'll report back with my findings.


Kind regards

Stan

Hi all

I have just experimented using scheduler codes to create music clocks. What I

tracks per hour and approximately 2hrs to create to create a day’s music log.

If I only use a group or groups with no codes it takes approximately 30 seconds 
to create an hour clock.

Could some one please tell me if this is the amount it should take to create 20 
tracks per hour? Anyone else experienced anything similar?

2 hours for a days log is 'typical' on a computer with a basic amount

You can make it go faster by using lots of RAM >8GB [and fast ram]

We cut creation time by about 1/4 with a high spec machine. It cost!

In the normal scheme of things we run log creation 8 days in advance

There is a system promoted by it's creator as 'faster than Rivendell'

Hi Robert

I will try creating a log using a much more powerful system. I am am 
using a library of approximately 60,000 which I did think I might have 
an impact but I'm only using very few options, just the one scheduler 
code per hour and a single group.

Re: [RDD] Scheduler codes time taken

2019-03-19 Thread Patrick
There have been some optimizations made to scheduler in Rivendell 3. I'm not 
aware of any issues with scheduler codes in the 2.x branch, but the stack that 
keeps track of carts for artist/title separation grows indefinitely which could 
severely slow down log generation. Rivendell 3 purges the stack during 
maintenance runs which helps to keep log generation quick.

Our Rivendell 3 beta system creates 24 hour logs in under a minute.

We're still on v2.10.3, but yes, it takes 4 hours to create one day's
music log of 432 songs using scheduler codes to separate rock and R 
We run 2 logs, one music only, the other stopsets and programs with
macros to switch between them.  On the other hand, takes only about 2
minutes to create a day's stopset log which does not use scheduler
codes.

[RDD] Scheduler codes time taken

2019-03-19 Thread Stan Fotinos
Hi all

I have just experimented using scheduler codes to create music clocks. What I 
am finding is that it takes approximately 5 mins to create 1 hour with 20 music 
tracks per hour and approximately 2hrs to create to create a day’s music log.

If I only use a group or groups with no codes it takes approximately 30 seconds 
to create an hour clock.

Could some one please tell me if this is the amount it should take to create 20 
tracks per hour? Anyone else experienced anything similar?

Centos 7 Rivendell 2.19.3

Thank you
