dCore Import Debian Packages to Mountable SCE extensions > dCore X86

Why does sce-update take so much time (even more than sce-import)?

<< < (3/6) > >>

sm8ps:
That sounds promissing! I am looking forward to testing any new versions.

Cheers!

Jason W:
It seems it is not so much the checking of all packages in an SCE that was causing the performance difference between sce-import and sce-update, but the sce-update routines needed to be adjusted with the changes made recently to sce-import.  Below is a comparison of the performance of sce-update before and after the changes made now.  All seems well, so sce-update has been updated, please test.

sm8ps:
Now that does sound exciting! The time savings really do look spectacular.

jls:
Hi
Thanks Jason for the update and sm8ps for pushing Jason
-f needs to be adjusted in sce-update -h

Jason W:
Thanks jls, -f option has been corrected in the -h help menu.
