sidedatacopies: fast path data fetching if revision has no sidedata...
sidedatacopies: fast path data fetching if revision has no sidedata When using the side data mode, we know their won't be any copy information sidedata. Skipping revision restoration give an important speed boost. In the future, there will be other user of sidedata, reducing the efficiency of this. We should consider adding a dedicated flag in revlog V2 to preserve this optimisation. The current situation is good enough for now. revision: large amount; added files: large amount; rename small amount; c3b14617fbd7 9ba6ab77fd29 before: ! wall 2.401569 comb 2.400000 user 2.390000 sys 0.010000 (median of 10) after: ! wall 1.429294 comb 1.430000 user 1.410000 sys 0.020000 (median of 10) revision: large amount; added files: small amount; rename small amount; c3b14617fbd7 f650a9b140d2 before: ! wall 3.519140 comb 3.520000 user 3.470000 sys 0.050000 (median of 10) after: ! wall 1.963332 comb 1.960000 user 1.960000 sys 0.000000 (median of 10) revision: large amount; added files: large amount; rename large amount; 08ea3258278e d9fa043f30c0 before: ! wall 0.593880 comb 0.600000 user 0.590000 sys 0.010000 (median of 15) after: ! wall 0.251679 comb 0.250000 user 0.250000 sys 0.000000 (median of 38) revision: small amount; added files: large amount; rename large amount; df6f7a526b60 a83dc6a2d56f before: ! wall 0.013414 comb 0.020000 user 0.020000 sys 0.000000 (median of 220) after: ! wall 0.013222 comb 0.020000 user 0.020000 sys 0.000000 (median of 223) revision: small amount; added files: large amount; rename small amount; 4aa4e1f8e19a 169138063d63 before: ! wall 0.002711 comb 0.000000 user 0.000000 sys 0.000000 (median of 1000) after: ! wall 0.001631 comb 0.000000 user 0.000000 sys 0.000000 (median of 1000) revision: small amount; added files: small amount; rename small amount; 4bc173b045a6 964879152e2e before: ! wall 0.000077 comb 0.000000 user 0.000000 sys 0.000000 (median of 12208) after: ! wall 0.000078 comb 0.000000 user 0.000000 sys 0.000000 (median of 12012) revision: medium amount; added files: large amount; rename medium amount; c95f1ced15f2 2c68e87c3efe before: ! wall 0.410067 comb 0.410000 user 0.410000 sys 0.000000 (median of 23) after: ! wall 0.207786 comb 0.200000 user 0.200000 sys 0.000000 (median of 46) revision: medium amount; added files: medium amount; rename small amount; d343da0c55a8 d7746d32bf9d before: ! wall 0.097004 comb 0.090000 user 0.090000 sys 0.000000 (median of 100) after: ! wall 0.038495 comb 0.030000 user 0.030000 sys 0.000000 (median of 100) Differential Revision: https://phab.mercurial-scm.org/D7074
