Date: Tue, 21 Sep 2010 18:59:05 -0600 From: Thomas Fjellstrom <thomas@...llstrom.ca> To: linux-kernel@...r.kernel.org Subject: rsync causing high loads on 2.6.36-rc4 This isn't something I remember happening with older kernels, but I just started an rsync from an nfs share over GbE, to a external SATA drive over usb 2, and I'm seeing both of my laptop's cores hitting 80-100% cpu use, two rsync processes are using 20-40% each, some kworker's are using tiny bits (2-10%), and kswapd0 is hovering around 5%. Quite a lot of the time seems to be io- wait. load average is almost at 6. This is a dual core T9400 core2duo laptop, with 4GB ram, running full amd64 (64bit 2.6.36-rc4 kernel and userspace). Its impacting desktop interactivity quite a lot. -- Thomas Fjellstrom thomas@...llstrom.ca -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
