I'm one of those people who have been removing yum-presto for exactly the reason that you describe (40Mbps connection, 4-core SandyBridge CPU). Would love to test this out.

I personally never noticed that, but maybe my download is that fast, the rebuild progress is so minor, it's invisible on the bar when the "rebuilding rpms" message shows. Anyway interesting..

Are you sure that's what it currently does?

yum-presto to get multicore support
For some people with fast connections/slow PCs, using deltarpms via yum-presto can be slower than downloading the full RPMs. Jonathan Dieter just did a Rawhide build (yum-presto-0.8.0-1.fc18) that adds multicore support to yum-presto. Would be interested if people would note what rebuild speed they get before and after updating to this version, and if the speedup is close to linear. My experience is that rebuilding drpms is CPU-bound so there's a good chance it will be. I'd also be interested if someone more familiar with the deltaiso code than me could venture an opinion as to whether the same basic approach would work for that. This is important because in recent years, networks have gotten faster but individual CPUs mostly haven't. This will help deltarpms to keep up. yum-presto build: http://koji.fedoraproject.org/koji/buildinfo?buildID=320054 RFE: Yum should use multiple threads to reassemble deltarpms https://bugzilla.redhat.com/show_bug.cgi?id=701711 -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
