             Summary: Performance decreasement migrating from 3.0.3 to 4.8.0
                 Key: LUCENENET-647
             Project: Lucene.Net
          Issue Type: Improvement
         Environment: OS: Windows 10

CPU: Intel Core i7-8700 

RAM: 32Gb
            Reporter: Mo Dje


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 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
