Hello, When using eCryptfs on a low end devices like NASs, the CPU is often limiting the performance of reading/writing dramatically because of the intense cryptographic workload. I know that using cryptography on such systems is always a trade off, but I ask myself about a possible optimization which would help very much: On my NAS the throughput with eCryptfs drops by about 70% (Synology DS412+, Atom D2700 - 2 Cores, Hyperthreading). For non-encrypted operation the CPU nearly idles, when using eCryptfs its at about 25% load. I assume that only one of the possible four parallel CPU threads are used. My question is "Will there be a multi CPU core version?" which would improve performance on low powered CPUs. I don't know, if this is the right place to ask, but it would be great if any of the developers could give me feedback if this will be possible in the future - crossing fingers :) Thanks.
