[jitsi-users] bad RAM and CPU performance


#1

Hi!

I noticed recently that Jitsi always was one of the programs that used
most of the CPU and RAM on my Netbook (running Windows 8). Maybe this
happens if you currently have no Internet connection, but Jitsi is
definately one of the few programms that drain the battery and will
cause the fan to start.

Is this a known issue?

There are plenty of tools out there for Windows that allow you to either:

1. Reduce a program's priority at will.
2. Lets you reclaim (=free) used physical RAM by forcing a swap to disk.

#1 that comes to mind is PRIO TASK MANAGER, Free for Personal Use
http://www.prnwatch.com/prio/

Of course, as soon as you get or make a video or voice call going, you
should bring the CPU priority of the Jitsi process to "normal".

Another is Process Lasslo, which lets you set certain rules to "tame"
running processes based on usage etc. But it isn't FREE.

#2 is RAMRUSH
http://www.fcleaner.com/ramrush.htm

It worked very well for me when I tested it.

I have tested neither with Win 8 as I don't use that lame excuse of an OS
yet. But being so simple apps, I bet #2 will work. Not sure about #1 as it
hooks into task manager... might require some vendor tweaks to support Win8
/ 8.1...

Thank you for the feedback!

Yes, Jitsi is one of the programs that noticeably and quickly drain
the battery for me on Windows, OS X (the power-related utilities on
these two operating systems report Jitsi as a considerable power user)
and Ubuntu. We're continually improving the performance of our
products and we expect the battery drain of Jitsi to reduce over time.

Has anybody done any profiling on Jitsi to see things like:

a) which code is using CPU cycles?

b) which JARs start threads?

c) which JARs hog memory?

If it is just a subset of optional JARs at fault, rather than fixing
them, maybe just make it easier to exclude them.

There certainly isn't any lack of Java profiling tools.

But in any case, the RAM is there to be used. The real solution is updating
RAM. A Netbook with 2GB barely has enough ram these days to run MSFT Win ...
