I hope that I am in the correct subforum...
Sadly, I am experiencing horribly slow write rates on an AES encrypted (luks) partition under Linux. I am using an Intel i5 6600K and a Gigabyte GA-B150-HD3P Board,
the Harddrive is connected to the USB 3 port and connected in USB 3 mode. The fact, that I am able to write to the second NTFS partition with about 70MB/s instead of 600KB/s,
which is the speed I get when trying to write a file to the AES partition. I dont think that this is supposed to be like this, because I can write to the AES partition with a speed of about
30MB/s with my laptop that features an i5 3320M Processor, also the i5 6600k does feature aes acceleration according to the ark.intel.com page.
Is there anything I'm doing wrong?
I will be more than glad to assist you with your concern.
Based on the information provided I will continue with the investigation of your concern.
As soon as I have further details I will let you know.
The https://ark.intel.com/products/88191/Intel-Core-i5-6600K-Processor-6M-Cache-up-to-3_90-GHz Intel® Core™ i5-6600K Processor (6M Cache, up to 3.90 GHz) Specifications does feature Intel® AES New Instructions but it also has to be supported by the BIOS and by the Operating System (I am not aware if Linux requires additional libraries to fully support it, see the following article: https://www.cyberciti.biz/faq/how-to-find-out-aes-ni-advanced-encryption-enabled-on-linux-system/ https://www.cyberciti.biz/faq/how-to-find-out-aes-ni-advanced-encryption-enabled-on-linux-system/)
I hope this helps,
rguevara thanks for your answer, according to the outputs, board does also support the aes-ni feature, but I will ask the question there again, thank you for your effort.
rguevara, thank you for the comments.
Sellerie, please submit the issue in the Intel Developer Zone Forum, they should be able to further assist you.
