Re: Is there a way to manually trigger GC?

Hi Phil, that function only reports available memory.

Hi Rick,

My application, the Time Saver's Toolbox, has a clipboard manager, and upon
loading the app, I load the existing archive of "clips" into memory.
Currently for example, the app is using 37 megabytes of system ram.
You are right, on-demand loading seems to be the only way i can have some
control over memory consumption.
Luckily I had enough foresight to keep a list of clips and their timestamp
without the data, so i can load that instead of the clips.

Thanks guys ...

Re: Is there a way to manually trigger GC?

2021-01-17 Thread Rick Harrison via use-livecode
Hi Tom,

Garbage Collection and releasing memory is not an
easy problem to solve.  It would be better to try to
figure out why your application is chewing up so
much memory on load.

Load times can be improved by only loading in
stuff that you absolutely need to access at the
moment to display to your user.  If you can stall
loading things until idle you may be able to smooth
out performance.  This is usually things like trying
to load tons of images all at once for a game etc.

On the plus side, the fact that memory use drops
down after load to under 100 mb is good.

If you are using a lot of images, are they part of
the stack or are you trying to load them after the
program is running?

Lots of things affect performance.  Try to think
of what might be hampering that.

Good luck!

Rick

Re: Is there a way to manually trigger GC?

2021-01-16 Thread Phil Davis via use-livecode

Hi Tom,

Does hasMemory() have any effect on available memory, or does it truly 
just report the state of things?


I wonder if there is some shell command that might help?

Hi Folks,

I'm finding my application does a nice job to unload data from memory, but
it takes a while for that to happen.  When the initial load of the
application occurs, the memory consumption is quite high if there is lots
of data to be loaded (1 GB+).

But after a while, the used ram drops down to under 100 mb as the
application run in the background, after which the application swaps is
only the data I am accessing.

Can I trigger that memory release manually? (Maybe its another mechanism
and not GC?!)

TIA
