From 77c4865bbde4cd2a061cf333f9ad798afc6de0ef Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 1 Jun 2015 22:16:17 +0100 Subject: sstate: Parallelise checkstatus calls for sstate mirror Currently the urls are checked serially which is a performance bottleneck when looking at http:// urls in particular. This adds code to check the url status in parallel, mirroring the way we do this elsewhere. We need the datastore for the fetcher so we use threads, not multiprocess.
