As a quick example of the effect of hardware compression I created a 728M file filled with random data from /dev/urandom:
Without hardware assist: # time gzip -c -1 /tmp/gzip.in >/tmp/gzip.out.gz real 0m35.471s user 0m25.735s sys 0m0.846s With hardware assist: time ./gzip -c -1 /tmp/gzip.in >/tmp/gzip.out.gz real 0m9.727s user 0m0.113s sys 0m0.749s Same test this time on 782M of all zeroes: Without hardware assist: # time gzip -c -1 /tmp/gzip.in >/tmp/gzip.out.gz real 0m3.814s user 0m3.600s sys 0m0.208s With hardware assist: # time ./gzip -c -1 /tmp/gzip.in >/tmp/gzip.out.gz real 0m0.389s user 0m0.061s sys 0m0.328s ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
