In such cases it would *really* be useful, in addition of dumping
80-100 raw numbers to summarize results and compare them for the
reader, as i suspect you've done already? Please don't keep it a
secret and don't force the reader to compare two tables with 80+ raw
numbers! :-)
Something like:
" In short, block writes are 20% faster, block reads are 19.9%
faster, seeks got 16% faster. None of the operations got slower. "
Thanks,
Ingo
