Silly question, but are we talking about comparable hardware (or identical)
between the two?

Re: Startup timing Windows vs. Mac

2018-12-09 Thread chris . gray 
Seconded.

When working in a mixed windows/linux environment, I've seen refactorings
which meant moving files between directories (e.g. move a package into a
different bundle under bndtools) take seconds on linux vs. *minutes* on
windows. If you have a lot of bundles, even the creation and population of
the fwdir could take significantly longer.

Re: Startup timing Windows vs. Mac

2018-11-21 Thread David Jencks 
A possible reason could be lots of DS services with greedy optional static 
dependencies started in different orders on the two OSs. If a service with such 
a reference is started first, it will get restarted every time a target service 
for the reference is started.

It still begs the question as to why you saw such a difference in times between

Hi JB,

Thank you for the clarification. I think the bundle load time on Windows was 
affected by a large number of services in the component. I don’t know exactly 
the reason, but how the OSGi container processes the bundle on startup was much 
slower on Windows because I had a large number of services. I reworked my 
architecture to reduce the number of service components and the startup time 
went down quite a bit.

Thank you,

Hi JB,

I don’t think the antivirus is an issue in my case.

I did disable Windows Defender. My test case is with a single bundle
that is installed via this command:

install reference:file://$eclipse_projects/sample.bundle.a


The location $eclipse_projects points to the local file system where
Eclipse projects for bundles reside.

From Active state I run command *update sample.bundle.a*

I see that the entire bundle start part of the update consists of two
parts. Right after the activation process starts I see a delay. No
logging occurs, even with the log level set to TRACE. Then log output
starts showing initialization of my bundle’s components/services.

The latter part runs quick on both Windows and Mac and take about 1 sec.
However, the former part that is silent and takes about 5 sec on Mac and
20 sec on Windows. So, 4 times slower on Windows.

What happens with the bundle at the start? Are files copied? I do
suspect it has something to do with the file IO.

Re: Startup timing Windows vs. Mac

2018-11-20 Thread Jean-Baptiste Onofré 
Hi Oleg,

bundle:update is roughly equivalent to bundle:stop, bundle:uninstall,
bundle:install, bundle:start. It gets the "new" bundle version from the
bundle location (that you can see with bundle:list -l).

Nothing suspicious in the bundle activator that could explain it takes
time to stop/start on windows ?

JB

 Hi Oleg,

 So Windows is longer than Mac (not surprising ;)).

 Did you check in term of bundles resolution ? Do the two systems use the
 same Maven repository and network to resolve the artifacts.

 I already saw such issue due to the Windows antivirus: it verified any
 artifacts downloaded by Karaf and it takes time.

 Do you have antivirus on the Windows system ?

I’d like to add that this bundle has many classes and a large number of 
services.

Re: Startup timing Windows vs. Mac

2018-11-20 Thread Oleg Cohen 
Hi JB,

I don’t think the antivirus is an issue in my case.

I did disable Windows Defender. My test case is with a single bundle that is 
installed via this command:

install reference:file://$eclipse_projects/sample.bundle.a 


The location $eclipse_projects points to the local file system where Eclipse 
projects for bundles reside.

From Active state I run command update sample.bundle.a

I see that the entire bundle start part of the update consists of two parts. 
Right after the activation process starts I see a delay. No logging occurs, 
even with the log level set to TRACE. Then log output starts showing 
initialization of my bundle’s components/services.

The latter part runs quick on both Windows and Mac and take about 1 sec. 
However, the former part that is silent and takes about 5 sec on Mac and 20 sec 
on Windows. So, 4 times slower on Windows. 

What happens with the bundle at the start? Are files copied? I do suspect it 
has something to do with the file IO.

Thank you,
Oleg

RE: Startup timing Windows vs. Mac

2018-11-20 Thread Leschke, Scott 
I can't speak to Karaf explicitly but there have been huge issues with both 
antivirus and disk encryption overhead in the Windows environment here.  
Encryption can really slow things down. All our laptops and desktops are 
encrypted on the fly.

While most have SSDs now, I have an old desktop that I no longer use with a 
hard drive that became effectively unusable.

Re: Startup timing Windows vs. Mac

Hi JB,

Yes, it is Windows. It is exactly the same set of bundles and the same Maven 
repository. Yes, there is Antivirus. I can try testing with disabling it 
temporarily. 

How can I see what is being resolved/checked/updated/downloaded? I do notice 
that Karaf has these long pauses. I am sure I can run pretty much against the 
local repo.

I would appreciate any pointers on how to speed up the startup!

Best regards,

Startup timing Windows vs. Mac

2018-11-19 Thread Oleg Cohen 
Greetings,

I have two systems: one Mac and one Windows. I have noticed that exactly the 
same application with a number of bundles, both 3rd party and my own, take 
significantly longer (1.5 vs 6 mins) on Windows compared to Mac. Both systems 
are pretty powerful and have similar resources. I was wondering if anybody has 
noticed the same. What would be the best way to analyze the startup performance 
and identify bottlenecks?

Thank you,
Oleg
