Nope. I know LZJB is not LZO, but I'm starting from a point of saying that LZO
is specifically designed to be super-fast, low-memory for decompression. (As
claimed all over the LZO webpage, as well as wikipedia, and supported by my own
personal experience using lzop).
So for comparison to LZJB, see here:
LZJB is, at least according to these guys, even faster than LZO. So I'm
confident concluding that lzjb (default) decompression is significantly faster
than zlib (gzip) decompression.
