I see some possible tuning options to imexpire (e.g. -t -r -m options). Can someone elaborate on these? I haven't found them documented too well. This is for specifically running imexpire interactively, rather than through a scheduled/cron.
If we have 30 partitions, by default it seems there will be one thread per partition, up to 50 maximum.
The goal is to run imexpire as fast as possible.
Can we bump the -r option to 2? So we end up with 60 threads etc... what is the impact?
