Angela Schreiber resolved OAK-8673. ----------------------------------- Resolution: Won't Do see OAK-9203 and OAK-9185 for recent improvements related to permission evaluation and additional benchmarks that highlight additional limitations associated with increasing the default maxsize. > Determine and possibly adjust size of eagerCacheSize > ---------------------------------------------------- > > Key: OAK-8673 > URL: https://issues.apache.org/jira/browse/OAK-8673 > Project: Jackrabbit Oak > Issue Type: Technical task > Components: core, security > Reporter: Angela Schreiber > Assignee: Angela Schreiber > Priority: Major > > The initial results of the {{EagerCacheSizeTest}} seem to indicate that we > almost never benefit from the lazy permission evaluation (compared to reading > all permission entries right away). From my understanding of the results the > only exception are those cases where only very few items are being accessed > (e.g. reading 100 items). > However, I am not totally sure if this is not a artifact of the random-read. > I therefore started extending the benchmark with an option to re-read a > randomly picked item more that once, which according to some analysis done > quite some time ago is a common scenario specially when using Oak in > combination with Apache Sling. > Benchmarks with 10-times re-reading the same random item: > As I would have expected it seems that the negative impact of lazy-loading is > somewhat reduced, as the re-reading will hit the cache populated while > reading. > Result are attached to OAK-8662 (possibly more to come). -- This message was sent by Atlassian Jira (v8.3.4#803005)
