Stefan Egli reopened OAK-1465: ------------------------------ reopening :) this degradation is there also in 0.18-snapshot (double-checked..) - but with much better overall figured, and slightly less dramatic: {code} # CreateManyIndexedNodesTest C min 10% 50% 90% max N Oak-Mongo 1 104 129 156 234 512 117 Oak-Mongo 1 107 130 163 224 277 119 Oak-Mongo 1 118 132 166 254 694 108 Oak-Mongo 1 118 146 178 247 961 101 Oak-Mongo 1 122 146 178 244 743 106 Oak-Mongo 1 125 147 185 242 402 105 Oak-Mongo 1 146 157 183 256 363 101 Oak-Mongo 1 140 160 192 249 1402 95 Oak-Mongo 1 152 163 195 264 545 95 Oak-Mongo 1 150 167 212 1563 4263 37 {code} > performance degradation with growing index size on Oak-Mongo > ------------------------------------------------------------ > > Key: OAK-1465 > URL: https://issues.apache.org/jira/browse/OAK-1465 > Project: Jackrabbit Oak > Issue Type: Bug > Components: mongomk > Affects Versions: 0.17.1 > Reporter: Stefan Egli > Attachments: CreateManyIndexedNodesTest.java > > > Tested with an oak-snapshot of Monday Feb 24, 10AM EST. > Noticed that when the amount of nodes indexed - eg wrt a particular property > - the adding of nodes becomes slower and slower. > Will attach a oak-run benchmark to underline this. Basically the scenario > where this occurred was: > * have a number of "level 1" nodes (eg 100) > * under those "level 1" nodes, add a growing list of children, each with a > property that is indexed (ie that index is actually growing and is probably > causing the slowdown). -- This message was sent by Atlassian JIRA (v6.1.5#6160)
