Note: all costs are according to cprofile on my machine, as a fraction of total time to import, python-flamegraph has somewhat different cost distributions, YMMV. Profiles use test-import of a 2500 partners file, with name, country, street and 0~4 tags, all randomly generated/assigned. Costs were profiled as split 8.5%/32%/57% between data conversion, creating records (Model.create/Model._create) and populating stored computed fields for a total import time (unprofiled) of 1mn (±2s or something). For the creation step, 27% (of total runtime) were assigned to the m2m (fields.Many2many.create), almost all of which (25%) was assigned to accessing a record's id in a listcomp in a loop. Optimisations: * optimise the case where we're only adding / creating values: represent the relation as a dict of sets instead of a set of pairs; commands 5 and 6 will only operate on the current record's value, instead of traversing all pairs in the relation * optimise accessing the value of an id field by hand-inlining the various bits, this is mostly obviated by the other previous optimisations (number of Id.__get__ calls reduced from 5.4 millions to 0.55) but given how common accessing a record's id is (and how it's usually considered to be free) it's still a good idea: cost of accessing the id field was reduced by 75% (0.55 million accesses went from 3.32% of total runtime to 0.83%) Without profiling, time to import my test file went from ~1mn to ~45s.
