Startup timing Windows vs. Mac

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

I suspect you're hitting this known Mac issue:

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.

Yes, first, please try with the antivirus disabled.

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.

Honestly, despite being a windows user, file fileio on linux/unix based

Re: Startup timing Windows vs. Mac

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.

RE: Startup timing Windows vs. Mac

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

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,
Oleg

bundle:update is roughly equivalent to bundle:stop, bundle:uninstall,
bundle:install, bundle:start. It gets the "new" bundle version from the

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

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://$eclipse_projects/sample.bundle.a
<file:///$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

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 ?

Re: Startup timing Windows vs. Mac

Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
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

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

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

Re: Startup timing Windows vs. Mac

Posted by Oleg Cohen <ol...@assurebridge.com>.
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://$eclipse_projects/sample.bundle.a <file:///$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

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,
Oleg

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 ?

JB
