Slow on update using WS

marcosvasousa

I found that the line is very slow final UpdateResult[] updateResults = repositoryServiceSoapBindingStub.update(cml);
It takes at first call 13 seconds and subsequentes call takes 5 seconds.

I put MYSQL logging query and no slow query founded. Also, I indexed the repository. No solution give to me good result.
Is it normal to take always between 5 - 13 seconds while update document? How can I speed my code?

Notes: The document created contains Version Label: 1589. If first tried search forum and no solution founded. Maybe consider this https://forums.alfresco.com/en/viewtopic.php?f=53&t=2056 as same!

Found below the code used. Please help me.

Please, can someone give to me any clue?

marcosvasousa

I tried alfresco version 4 enterprise trial and founded that updating an document with history/versions tooks to long also!

See numbers:
Alfresco 4 Enterprise Trial:
659 ms while updating an document with 39 history
1583 ms while updating an document with 185 history

Alfresco 3 Community:
722 ms while updating an document with 39 history
5289 ms while updating an document with 185 history

Is this normal numbers? Alfresco looks to be slow while more documents are being created!

mrogers

Well at least alfresco 4 is faster.

Yes there seems to be an issue there. Not sure why document history is having that effect. However your system still seems to
be running slowly. First thing to check is the amount of RAM configured.

Also I suggest you don't continue to use a deprecated API.

marcosvasousa

Yes, looks like Alfresco 4 is very fast!

I read the http://chemistry.apache.org/java/0.4.0/maven/apidocs/org/apache/chemistry/opencmis/client/api/Document.html and found "boolean refresh". If use false Alfresco 4 is fast:

Alfresco 4 Enterprise Trial (Linux 64 bits):
329 ms while updating an document with 39 history
635 ms while updating an document with 185 history
…
752 ms while updating an document with 250 history
…
With 1000 documents without refresh, the times decrease from 7 seconds to 3.8 seconds.

We are under JVM memory: "server -Xss1M -Xms3G -Xmx6G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewSize=1G -XX:MaxPermSize=256M -XX:CMSInitiatingOccupancyFraction=80 -"
so I don't think RAM is problem!!!
The machine has 8GB RAM.
Our Linux machine monitoring didn't indicates problems related to memory or disk!

Let me post my new code, so I really believe no longer using deprecated API in Alfresco 4!

marcosvasousa

Below found complete code used.
All my test showed to me that Alfresco will be slow while updating an document with version. Strange why document history do this effect!
What do you advice to me? Remember we are using Alfresco 3 Community in production.
Any additional information that can I provide to you?

See ALF-2713. There was a problem fixed in 3.3 timeframe and a note that the time still increases linearly.

Interestingly there were some timings associated with that fix, may be worth comparing your results with those.

marcosvasousa

Thanks.
Let me check if there is an patch/diff to apply to version 3.2 to resolve fast as possible.

We are currently installing Alfresco Community 3.4 to check this issue is resolved and to decide between:
> Migrate to Alfresco 4
> Upgrade to Alfresco 3.4
> Patch version 3.2 with fix from ALF-2713

While investigating Alfresco 4, I found that a document with 795 history:
getAlfrescoSession: 93 ms.
getCmisObject: 759 ms. - Using session.getObjectByPath
setContentStream: 147 ms.
updateProperties: 746 ms.
Total: 1746 ms.

marcosvasousa

We tested "> Upgrade to Alfresco 3.4" so we didn't found problems (no code upgrade/change is needed) and after 700 documents in history the time is below 200 ms.
So, we are now Upgranding to Alfresco 3.4.
