solr 1.4 memory jvm
Hi,
Sorry I can't find and issue, during my replication my respond time query
goes very slow.
I'm using replication handler, is there a way to slow down debit or ???
11G index size
8G ram
20 requests/sec

Is it a problem ??

We do not have such high update frequency. So we never encountered
this problem. If it is possible to take the slave offline during auto
warming that is a good solution.

Re: solr 1.4 memory jvm

Hi Noble,
Yes exactly that,
I would like to know how people do during a replication ?
Do they turn off servers and put a high autowarmCount which turn off the
slave for a while like for my case, 10mn to bring back the new index and
then autowarmCount maybe 10 minutes more.
Otherwise I tried to put large number of mergefactor but I guess I've too
much update every 30mn something like 2000docs and almost all segment are
modified.
What would you reckon? :( .... :)
Thanks a lot Noble

So what I decipher from the numbers is w/o queries Solr replication is
not performing too badly. The queries are inherently slow and you wish
to optimize the query performance itself.
am I correct?

Re: solr 1.4 memory jvm

Hi,
So I did two test on two servers;
First server : with just replication every 20mn like you can notice:
http://www.nabble.com/file/p22930179/cpu_without_request.png
cpu_without_request.png
http://www.nabble.com/file/p22930179/cpu2_without_request.jpg
cpu2_without_request.jpg
Second server : with one first replication and a second one during query
test: between 15:32pm and 15h41
during replication (checked on .../admin/replication/index.jsp) my respond
time query at the end was around 5000msec
after the replication I guess during commitment I couldn't get answer of my
query for a long time, I refreshed my page few minutes after.
http://www.nabble.com/file/p22930179/cpu_with_request.png
cpu_with_request.png
http://www.nabble.com/file/p22930179/cpu2_with_request.jpg
cpu2_with_request.jpg
Now without replication I kept going query on the second server, and I can't
get better than
1000msec repond time and 11request/second.
http://www.nabble.com/file/p22930179/cpu_.jpg cpu_.jpg
This is my request :
select?fl=id&fq=status_published:1+AND+status_moderated:0+AND+status_personal:0+AND+status_private:0+AND+status_deleted:0+AND+status_error:0+AND+status_ready_web:1&json.nl=map&wt=json&start=0&version=1.2&bq=status_official:1^1.5+OR+status_creative:1^1+OR+language:en^0.5&bf=recip(rord(created),1,10,10)^3+pow(stat_views,0.1)^15+pow(stat_comments,0.1)^15&rows=100&qt=dismax&qf=title_en^0.8+title^0.2+description_en^0.3+description^0.2+tags^1+owner_login^0.5
Do you have advice ?

Let me assume that the graph shows the CPU idle time. How do I know
that the spikes are during the replication
It is possible that you observe CPU spikes soon after the replication
because that is when you will have very few cache hits . Because
searches are done live.
Even if the index is very large the download is not CPU intensive. We
have done perf studies end which showed low CPU usage with large index
downloads ( 6GB)
To verify this , just setup a temporary slave which does not serve any
requests and do a replication and see the CPU usage

Hi Noble
I turnd off autoWarming to zero.
And yes it's during it replicate, it takes all the data index.
Because it merges too much, too much update 2000docs every 30mn, it always
merge my index.
So the replication bring back all my data/index.
which use a big part of the cpu like u can see on the graph, the first
part>>
http://www.nabble.com/file/p22925561/cpu_.jpg cpu_.jpg
and on this graph and first part of the graph (blue part) it's just
replication no request at all.
normally i've 20 request per second
what would you reckon ?

hi sunnyfr,
I wish to clarify something.
you say that the performance is poor "during" the replication.
I suspect that the performance is poor soon after the replication. The
reason being , replication is a low CPU activity. If you think
otherwise let me know how you found it out.
If the perf is low soon after the replication is completed. I mean the
index files are downloaded and the searcher is getting opened, it is
understandable. That is the time when warming is done. have you setup
auto warming?
