Niklas Gustavsson updated FTPSERVER-264:
----------------------------------------
Fix Version/s: 1.1
Assignee: Niklas Gustavsson
> It takes about 1 minute and 100% CPU to set a "wide" passive port range
> (org.apache.ftpserver.DefaultDataConnectionConfiguration$Passive.SetPorts())
> ----------------------------------------------------------------------------------------------------------------------------------------------------

> Key: FTPSERVER-264
> URL: https://issues.apache.org/jira/browse/FTPSERVER-264
> Project: FtpServer
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.0.0-M2
> Environment: Windows
> Reporter: Fred Moore
> Assignee: Niklas Gustavsson
> Fix For: 1.1
>
>
> We observed a long (about 1 minute) plateau of 100% CPU when trying to
> setPorts() in org.apache.ftpserver.DefaultDataConnectionConfiguration$Passive
> with "wide" port ranges such as 2122-65535.
> We observed that FTPServer internally performs an apparently very expensive
> scan on this range.
> Can this be made less CPU intensive and quicker (to shorten server downtime
> and reduce resource consumption in production)?
