Subject [jira] [Updated] (LUCENENET-647) Performance decreasement migrating from 3.0.3 to 4.8.0
Date Thu, 05 Mar 2020 15:23:00 GMT

     [ https://issues.apache.org/jira/browse/LUCENENET-647?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mo Dje updated LUCENENET-647:
-----------------------------
    Description: 
Hello,

I'm currently migrating a project, that uses Lucene.Net, from .Net Framework to .Net Core.

I had to migrate from 3.0.3 version of Lucene to 4.8.0 (beta0007) but I noticed performance
decreasement while measuring response time while requesting the database. The response time
using Lucene 4.8.0 is two to three times higher than 3.0.3 version.

I read some forum topics where other users noticed this performance decreasement too. Are
you aware about that? Do you plan to do something to improve performances of Lucene 4.8.0?

Best regards
