Does anyone have any tools or thoughts on how to turn live traffic (from log and/or tcpdump) into test load for a write-heavy site? (I've found this useful for regression testing and performance in the past on a mostly readonly site).<p>At the least, it would seem to require a storage snapshot (db+backend storage) timed with the beginning of the log capture, so to get correct responses.<p>The test could then consist of checking all HTTP responses are the same, and that the db+storage has changed in the same way in the test env as it did on live.<p>With our current setup (mysql+webdav storage) this seems challenging, particularly since both of these are very large.<p>Is anyone aware of any tools or work in this area?
