Hello, I am looking to purchase a supported crypto accelerator. Not for performance, but to off-load the CPU. The soekris hifn products are cheap and easy to obtain, but Googling yields a lot of posts that indicate there may be problems with the hardware. Safenet seems to be the other option (though I have yet to find a reseller) - but I have not found a single post anywhere about anybody's experience using it with geli in particular, nor FreeBSD in general. Does anyone have any recommendations regarding this? All I care about is low CPU usage and stability; performance is secondary. As a bonus, if anyone has CPU usage benchmarks for geli I'd be interested in seeing them. I did find one comparison while Googling, but it was completely inconsistent with what I am seeing. I am seeing complete CPU saturation doing sequential I/O on a USB device at about 10 meg/sec. (Actually 50% system utilization on a dual-core 3800+, which I take to be one core saturated unless geli is able to use both CPU:s for the same userland I/O operation.)
