Hi Jari, I saw that you changed the default nice value for the loop device when the kernel is using mingo's sched. If I remember that value was -9. Did you choose '-9' as a + - arbitrary value under 0, but over -20, or it has some special reason to be -9 and not -5 for exemple? regards, greg ps: in the past I experimented with renice-ing the loop to +5, it seemed better than -20, but sometimes I experimented temporal hangs when the machine had to write out encrypted data excessivly. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
