Hi Wentao,
The log excerpt shows that the getRepositoryInfo call takes most of the
time. Why it takes that long should be answered by a FileNet expert
(Jay?).
The log excerpt also shows that you are creating a new OpenCMIS session
to your FileNet server on the bridge. If you can cache the OpenCMIS
session object on the bridge, you avoid the getRepositoryInfo call and
save a lot of time.
Probably you already do that but your cache evicts the session object at
some point. The next request has to set up a new session that then calls
getRepositoryInfo again, which takes time. That would explain why it
suddenly gets slower.
Does it stay slow or do you only see spikes?
Are you using HTTP sessions and cookies for the cache? If so, does the
client always send the correct (current) cookies?
Btw. Use the Browser Binding, if you can. It's faster.

Hi,
We have a custom code which can't use OpenCMIS Client library, we
asked them to use pure http call by assembly the getContentStream url
with http basic header. The access is via cmis bridge (version 0.10)
to backend FileNet CMIS.
The call was fast (less than 3 second) at the beginning, but after a
few days, it become slow, the response time was 20 seconds until we
restart cmis bridge instance, access log as below

I am wondering if there were any resources not been released properly
when we use http call directly, any ideas where the slowness may come
from? The other client apps using opencmis java or .net library do not
have this issue.
Thanks
Wentao
