[bitbake-devel] [PATCH] use multiple processes to dump signatures.

[Jianxun Zhang]

RP,
I appreciate your multiple hints on the road for this issue! I do _feel_ this patch needs some improvement or tests, but I cannot identify them in my sight. Well, things shouldn’t be such easy with a V1 due to the complexity.

That’s why I have to hand over the burden to you. :-) Feel free to let me know any new possibilities.

I am actually interested in the data you shared. I improved my sig-dumping over 10 times (14.4 sec to 1 sec). Your test should covers other steps, so the improvement on sig dumping is less significant, 325.08 to 93.93 sec.

Maybe we should find some time to investigate any room to speed up the rest in test suite...

Thanks
