I've come across another solution that this would be useful. In the testing of filesystems with compression enabled (zfs, btrfs). Trying to figure out raw write speeds using /dev/zero is meaningless because the data is highly compressed. Using /dev/urandom is too slow (~ 6MB/s). Based on this post from stackoverflow (http://serverfault.com/questions/6440/is-there-an-alternative-to-dev- urandom) I tried:
time openssl rand 1000000000 | head -c 1000000000 > testfile which worked ok. But being able to use dd with erandom would be ideal for this situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/575669 Title: Rapid depletion of entropy pool -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
