This is a short series I extracted from a larger topic on reusing "external"[^1] deltas during verbatim pack reuse. As part of performance-testing that series, I realized that bitmap lookup tables are not written by default. Since it has been a significant period of time since their introduction, the first patch of this series makes writing the lookup table extension the default behavior. This is: * pack-bitmap: write lookup table extension by default The next three patches clean up some t/perf scripts that were redundant now that lookup tables are the default behavior. Those are: * p5312: removed duplicate performance test script * t/perf: avoid testing bitmaps without lookup table * t/perf/lib-bitmap.sh: avoid test_perf during setup Thanks in advance for your review :-). [^1]: The term I'm using to describe delta/base pairs which either (a) are represented from different packs in a MIDX bitmap, or (b) the client is known to already have the base.
