We are migrating our apps from OS X Server 10.4 to CentOS Linux
(x86_64), and everything is working fine. But I did notice
something :
wotaskd and JavaMonitor are eating a lot more RAM. On the OS X box,
they
take 41 MB each, on Linux they take up to 140 MB each :-/
The JVM on OS X is :
Java HotSpot(TM) Server VM (build 1.5.0_13-121, mixed mode)
On Linux :
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)
So both are running the Server VM, the only different is Java 6 vs 5,
and 32 bits vs 64 bits. Still, I'm a bit amazed that it takes
triple the
RAM. Both machines are running the same apps and the same number of
instances.
Anyone have seen this? It's not a problem, I just think it's a bit
strange.
A few weeks ago I noticed that some of the wotaskd that were running
were just in the top of memory consumers.
Actualy I have a wotaskd which has 42 instances running consuming
~285Mo (resident memory), it's a Wonder version
(06-01-2010 build for WO 5.3) running under Java 1.5 on an x86_32
Linux.
I noticed that Monitor consume memory too but less than wotaskd.
I had the idea of switching back to a vanilla version but profiling
would be more helpful to understand why it's eating
so much memory.
Hum, I forgot to say that I also moved from the bundled version of
wotaskd/Monitor to the Wonder versions. So since the Linux box is not
in prod, I switched back to the 5.4.3 Apple version of the tools, and
Monitor is eating 68 MB, wotaskd is eating 62 MB. If I switch back to
the Wonder versions, wotaskd eats 107 MB, Monitor 73 MB.
So look like for whatever reason, Wonder's wotaskd eats almost double
the RAM than the vanilla one :-/
