So I wanted to do something like: for f in `seq 0 5 100`; do pgbench -T 180 -c8 -j8 -b tpcb-like@$f -b select-only@100 done; But, I'm not allowed to specify a weight of zero.
Indeed. I did not envision such a use case, but it is quite legitimate and interesting! I would hope that the behavior would be a linear combination of the raw performance of each script, but whether it is indeed the case is not that sure.
Would this be a welcome change?
Speaking for myself, I would be fine with such a change, provided: - that it does work:-) I'm not sure what happens by the script selection process, it should be checked carefully because it was not designed with allowing a zero weight, and it may depend on its/their positions. It may already work, but it really needs checking. - I would suggest that a warning is shown when a weight is zero, something like "warning, script #%d weight is zero, will be ignored". - the documentation should be updated:-) -- Fabien -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
