the ssd has a sandforce controller with buildin compression. Sequential speeds for random data are ~200MB/s read, ~130MB/s write. 4k random data write with one thread is ~55MB/s, ~115MB/s with 64 threads. It looks like the encryption transforms the 0-data stream in a more or less random data stream.
-- writing to ecryptfs partition on SSD drive is many times slower than writing to unencrypted partition on the same drive https://bugs.launchpad.net/bugs/654764 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
