Multi Threading - Creation of RMAP map

Hi,
I am currently on v15.2 (b071514) registered - My current map export to RMAP takes 10 hours (Pure vector data being exported)
When exporting to GeoTIFF I am able to script the export and run multiple sessions (7) that create 7 tiles at a time so I save a great deal of time.
Exporting to RMAP seems to create a new temp folder for each session, so even though I have set the option to not overwrite existing files they do not see each other so no saving is gained.
Is there a way to improve my throughput? Currently each session uses about 13% cpu usage.
Will there be a future update that will help with this?
best regards,
Brian.

Hi Brian,
To clarify: are you running your RMAP export using a script?
Unfortunately, at this time we don't have a good way to speed this up, given the temporary folder issue you mention. I have added item #15194 to our task list to address this issue. We will post to this thread when the status of this item changes.
Cheers,

Actually for the rmap export I am just running it from the application as there doesn't appear to be any benefits by running a script. Or is there something I am missing?

We are working on multi-threading raster and tiled exports right now, so hopefully by the v16.2 release in a few months a single export will be able to take advantage of multiple threads and be much faster.
Thanks,

That's good to know, thanks.
