Description
In RevisionGC on Oracle, performance of deletes is bad. Using RevisionGCTest:
VersionGCStats{ignoredGCDueToCheckPoint=false, canceled=false, deletedDocGCCount=92092 (of which leaf: 92000), updateResurrectedGCCount=0, splitDocGCCount=1, intermediateSplitDocGCCount=0, iterationCount=2, timeActive=7.429 min, timeToCollectDeletedDocs=1394 ms, timeToCheckDeletedDocs=250.4 ms, timeToSortDocIds=374.0 us, timeTakenToUpdateResurrectedDocs=17.00 us, timeTakenToDeleteDeletedDocs=7.399 min, timeTakenToCollectAndDeleteSplitDocs=97.95 ms}
Performed RevisionGC in 7,429 min
Compared with DB2:
VersionGCStats{ignoredGCDueToCheckPoint=false, canceled=false, deletedDocGCCount=96096 (of which leaf: 96000), updateResurrectedGCCount=0, splitDocGCCount=1, intermediateSplitDocGCCount=0, iterationCount=2, timeActive=8.240 s, timeToCollectDeletedDocs=1780 ms, timeToCheckDeletedDocs=259.7 ms, timeToSortDocIds=237.0 us, timeTakenToUpdateResurrectedDocs=19.00 us, timeTakenToDeleteDeletedDocs=4.552 s, timeTakenToCollectAndDeleteSplitDocs=685.4 ms}
Performed RevisionGC in 8,243 s
