cpu utlization is already on higher end, so VM wont seems a solution

One more idea could be is to have multiple vm's (8 cpu each) on your server
and load balance them. That would help Solr6 scale nicely

25 of 32 CPUs loaded is 78% CPU, but I’ve never seen CPU use reported that way.
How are you measuring CPU usage? What tool?

If the community cannot help, the only way i can think is either to profile
Solr (java) under a load test to find the problem. You could also use an
APM.

Yes, but how to move ahead now.
Its strange solr4 is better behaving than solr6

This would then mean that solr6 is reaching some kind of saturation (number
of threads, etc) at about loads of 60 Hits which then drives the
performance of it to be very bad !

100% CPU will cause congestion and very slow response.
In production, we do not drive Solr over 75% CPU.
He is reporting load average, which is a bit harder to interpret. When the load
average reaches the number of CPUs, that is probably the beginning of
congestion. But I’m less sure about that
I cant test on more as performance is already degraded.
Its a 32core system and load 25 means 2500% cpu

Please test for higher number of hits till cpu load reaches 100%

I would suggest to keep the load same both for solr4 and solr6. And then
test. Also please post exact concurrent hits

Hi Birender,
Do you monitor you heap? Is it possible that you are running close to max heap
size and that GC is what is taking CPU?

Also can you please post the throughputs for both of your tests

Yup. Improvement of response time would hurt the cpu usage. The other thing
is more memory usage (cache) which gets included into the cpu usage.

I have upgraded Solr4.0 Beta to Solr6.6. The Cache results look Awesome but
overall the CPU load on solr6.6 is double the load on solr4.0 and hence I
am not able to roll solr6.6 to 100% of my traffic.
*Some Key Stats In Performance of Sol6 Vs Solr4*
Document cache usage increased from .98 from .14
Other resource is not using the cpu.
Its true that response is better to 300ms from 350ms but cpu usage almost
doubled?

Two things trouble me:
1. It is a shared resource, so results are unreliable
2. Since cache results have increased, memory access will increase and it
will result in an increase in cpu usage. However response times will also
improve
To support more load you will have to increase server capacity
Config : 64GB RAM 32 CORE CPU
but i have given 20Gb to solr JVM.. Also its a shared resource

Can you please give the configuration of your server?
