Very looong time to read/write

[elconfa]

Hello, I'm using a CX5130 PLC and my program use about 8500 persistent vars.
I have a big problem reading/writing persistent vars: It takes a lot of time (about 45minutes using v.1.2.16 or 35 minutes using v.1.1.51).
Attached is the file of vars.
Backup_2021-12-09-172159 new 1.2.16.zip

What do you think about this problem?

update: using v.1.0.27 installed in PLC it takes 8 minutes to read vars and 1,5 minutes to write them. (15.000 vars)

Hi!

I can reproduce this very annoying performance issue. Sorry for that and thank you for reporting the problem here.
The search function for persistent symbols sadly has very bad performance, it can be optimized and made parallel.
The performance difference between version 1.0 and 1.1 regards the search depth. The version 1.0 was just able to find global persistent variables, 1.1 looks for persistent variables or even fields in every depth.

I will give a look and will try to optimize the search procedure and make an option for looking just for global variables.

Best regards,
FB

Hi, I've tested the last version (1.2.17) vs the old version (1.0.27).
The new version needs 6 minutes and 30 seconds, while the old version needs only 22 seconds.
This is only to remember this issue.
Thank you for this project

Hi!
Wow, this is impressive.
Did you already tried to use the "global only" flag?
Would you be able to share the variables (even obfuscated) or the logfile of a reading with the newest version?

In order to activate the logfile just put the log.config near to the exe.

Thanks.

I've used the "global only" flag.
This is the log.config
log.zip
Hope you can find the problem.
Thanks

Thanks.
You missed out the log folder and you just sent the log.config. Can you please send the file logs\TwinCatAdsTool*.log ?

I downloaded the file log.conf and putted it in the same folder of TwinCatAdsTool_ReadyToRun_v1.2.17.exe
I launched the program, but no logs directory was created... I'm sorry
