Hi,

I don't think it's usually a good idea or tip to skip files with AV.

HDD are not so expensives actually, just buy a faster one or think about upgrading to VIM ;).

Hopefully the developers at Sun are using DTrace on Solaris to pinpoint disk activity. I agree NetBeans still has room for improvement in the performance department, but it has come a long way from where it was in 5.x or even 6.0/6.1. I remember thinking 6.5 was the first usable version of NetBeans, but it still had some performance issues. I may have thought that because I switched to developing on Linux around that time.

Anti virus is only part of the problem, worse is excessive I/O from the numerous index files; a proper database engine uses far fewer files, and far more memory caching!

When I compare JBuilder 2006 (old) with NetBeans 6.7.1, JBuilder 2006 is often faster e.g switching file tabs is instant, no update delay at all for the source structure pane.

The NetBeans 6.7.1 source structure pane is still incredibly primitive and slow, it re-renders the whole pane, when an minor update render would be vastly faster, and not even necessary when switching loaded files!

I was wrong about NetBeans mapping everyting to a file on disk. It has a virtual filesystem in memory, but most things don't end up on disk. There is quite a bit of work going on to reduce *unnecessary* disk activity

I'm using ESET NOD32 Antivirus 4 on Windows Vista. Someone from Sun pointed out that making antivirus skip the NetBeans installation directory won't make much of a difference since the majority of the disk activity happens in .netbeans under your home directory.

I think another thing that affects performance is the type of development you are doing. I do Java EE web development with Maven which I think may be slower than a regular Java SE NetBeans project.

Unfortunately with McAfee VirusScan Enterprise, we don't have the option to disable anything. If you find other speed-ups... pass them on!

What about excluding the 'build' and 'src' directories of your projects? They contain executables that are rebuilt several times a day, which, I would expect, should trigger any good virus checker and cause unnecessary scans. I don't use Windows so I can't try it myself, but should be worth a try.

Uhm - which AV are you using?
Here at work we're using Sophos and I have never experienced a problem like that (winXP, NetBeans 6.7)

@Karsten : I think it has to do with how NetBeans plugins work. I'm not a NetBeans Platform/plugin developer, but I'm pretty sure that absolutely everything in NetBeans maps to files on disk, like menu items, tree nodes, etc. NetBeans does a lot of disk IO. I'll ask some platform developers to comment.

That is great that you found it out. I see also my Netbeans become unresponsive if I leave it open, but not use it for some hours.

I think disabling the virus scanner can not be the solution. Our clients need to trust us that we deliver virus-free software, so the scanner needs to check also Netbeans itself for infections, even when an infection is unlikely.

There must be a reason that the virus scanner slows Netbeans down, and this reason needs to be attacked.
