Yang Xia updated TINKERPOP-2855: -------------------------------- Priority: Critical (was: Major) > Performance degradation in TinkerGraph 3.5.4 and 3.5.5 > ------------------------------------------------------ > > Key: TINKERPOP-2855 > URL: https://issues.apache.org/jira/browse/TINKERPOP-2855 > Project: TinkerPop > Issue Type: Bug > Components: tinkergraph > Affects Versions: 3.5.4, 3.5.5 > Environment: Ubuntu 22.04.1, docker > Reporter: Gleb Sinyavskiy > Priority: Critical > Labels: bug, performance > > Hello, > I few days ago I tried to update gremlin-server in our project from 3.5.3 to > 3.5.4 and found out that it's test suite got 5 times slower. We use the > official docker image(tinkerpop/gremlin-server) with some configuration > changes: > {code:java} > gremlin.tinkergraph.vertexIdManager=ANY > gremlin.tinkergraph.edgeIdManager=ANY {code} > The app uses user-generated string ids and heavily relies on the upsert > pattern from the [recipes|https://tinkerpop.apache.org/docs/3.5.4/recipes/]. > Yesterday I made an investigation and narrowed it down to the performance of > the upsert pattern. I also discovered that the issue is not related to our > configuration changes and can be reproduced with vanilla image and LONG ids. > I prepared a [simple script that reproduces the > issue|https://github.com/zhulik/gremlin-server-performance-issue/] and > contacted Stephen Mallette on discord. They confirmed the issue exists, but > only in 3.5.4, 3.6.0 performs as expected. They also wrote a groovy script > that reproduces the problem: > {code:groovy} > g = TinkerGraph.open().traversal() > batches = (0..<100).collect{ (0..<100) } > start = System.currentTimeMillis() > for (batch in batches) { > b = g > for (id in batch) { > b = b.V(id).fold().coalesce(__.unfold(), __.addV("test").property(T.id, > id)) > } > b.iterate() > } > System.currentTimeMillis() - start > {code} > [discord > message|https://discord.com/channels/838910279550238720/838910279550238723/1064964247823593502] > Both my and Stephen's scripts perform a few times slower when executed > against 3.5.4 in compare to 3.5.3 or 3.6.0. > *Steps to reproduce:* > Run my or Stephen's script against vanilla tinkerpop/gremlin-server:3.5.4 > docker image > *Expected result:* > Script's execution time matches it's time when executed against 3.5.3 or 3.6.0 > *Observed result:* > The script is 5-7 times slower. -- This message was sent by Atlassian Jira (v8.20.10#820010)
