I am also experiencing this on a brand new 9.04 64-bit server installation on a very capable machine (Xeon 5520, 8GB RAM, HP SA RAID controller).
With one thread writing to the encrypted volume the system slows down with 2 kcryptd threads at 50-75% and ~6.00 load. With two threads writing to the encrypted volume the system becomes nearly completely unresponsive with a load average around 15-16. Re-nicing the kcryptd threads to 0 (changed from -5) makes the system much more responsive but does not improve read/write speeds at all. I'm getting read speeds around 20MB/s under load, 40MB/s when idle. I'm seeing reads at over 200MB/s on the unencrypted portions of the volume. -- kcryptd process doesn't utilize multiple cpus https://bugs.launchpad.net/bugs/246413 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
