My Linux server spend much time with LUKS encryption. Is there any way to hardware accelerate it (with a PCI express card for example)
Beginning with Kernel 2.6.32 the AES-NI instructions on newer Intel processors are supported by dm-crypt. You might want to check /proc/cpuinfo if your processor supports these instructions. Otherwise, upgrading your processor will speed up your harddisk encryption (provided you are actually using AES encryption)
