Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG 3.2-STABLE System: Dual P3/500 with 512MB RAM with Adapatec 2049U2W controller connected to two disks (9GB and 18GB). 18GB is a Seagate ST 318275LW camcontrol shows that this is capable of 80 MB/s with Tagged Queuing Enabled I have a tar file of around 1.6 GB. The directory tree is not very deep These are the times I am getting for untar the tar file on the 18GB disk. Also, times for rm -rf of the directory created Softupdates enabled Real User Sys untar: 13043.72 14.19 434.53 rm -rf 7036.8 8.05 172.84 I looked at the results from iostat in another virtual console and I was getting around 0.8 MB/s. Top was showing the machine mostly idle in CPU usage Mounting with async mode (single user mode) untar: 10799 13.17 462.69 rm -rf: 6537 7.82 259.64 The normal sync mode took quite a while also. I seem to have misplaced the numbers As a totally unscientific comparision. These are the untar times of glibc-2.1.1 on a softupate system glibc untar: 49 1 3.66 glibc rm -rf 2.06 0.05 0.88 Are these times appropiate ? Is there any way to make the untar go faster. What does 80 MB/s really mean in real-life ?
