[jira] Updated: (HARMONY-2288) [Classlib][performance] writting to file is highly ineffective

     [ https://issues.apache.org/jira/browse/HARMONY-2288?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ivan Volosyuk updated HARMONY-2288:
-----------------------------------

    Estimated Complexity: Advanced  (was: Moderate)
             Description: 
[A performance bug]
I have tried to display exception message on the screen and found out that each character is written using separate write() call.

Each character is written via calling native method:
  Java_org_apache_harmony_luni_platform_OSFileSystem_writeImpl()

It is possible that this code is also responsible for writting into files. We should do something with this to have acceptable performance!
