Hey Milan, thank you for spending time on the long awaited multi-core-crypto-support!

The test results are included as text-file as I fear the syntax of the bonnie output will suffer if included directly in the mail, so please exuse using an attachement. I hope most MUAs will end up displaying it directly. > (but there is still some issues and it will not help much > if only one process generates IOs.) Are you sure about that? Actually I also observed quite some performance gain for single process IO. In case you would like me to do some other comparisons, feel free to point me in the right direction. So far I also did not take time to check if it ends up eating the data, but if it fails, I guess my desktop will let me know. Hooray for the backup and black-magic-kernel-patch-users. ;) By the way: As it seems, compiling the patched kernel breaks, if trying to compile the AES stuff as modules. Tobias
