Pale Moon profile backup tool: only runs in single thread?

[jobbautista9]

I've been using this [profile backup tool](http://www.palemoon.org/backuptool.shtml) to quickly backup my 33.9.1 profile before upgrading it to a 34.0.0 prerelease, and it seems to still work well, both backup and restore that is.

I do wonder if the 7zip compression can be modified to use multiple threads instead of a single one though. Compressing a 2 GB profile can take a long time... The 7za.exe included doesn't seem to support multithreading at all.

I don't think this is going to make sense in this context. If you're compressing multiple large files independently, threading is meaningful. If you're compressing a lot of small files together, the best compression ratio would be achieved by treating all the files as one large data source, thus one thread.

The 7za.exe included doesn't seem to support multithreading at all.

Probably does not (probably proceeding multithreading by a few years).

(Does that need any update for security reasons?)

Have you tried backing up your Profile data (manually) using current 7-zip, using multithreading, to see if there would be any actual (speed) advantage? (Seemingly LZMA2 only supports 1 or 2 threads, & whether 1 or 2 are used depends on the individual data file sizes, & given what one might expect in a Profile, & as pointed out, you're not apt to have large enough files for it even to come into consideration, even with 2 GB total size. You can adjust some parameters to 7-zip to try to force multithreading... but throw current 7-zip at your files & see what you get.)

I guess I could make a maintenance update to include a current 7za (there shouldn't be any sec concern -- not like it'll be used for anything other than profile data and own-packed archives). Does mean I have to get Neobook set up properly again to compile the package and re-sign it.
