There is a profiling tool in Eclipse that can show you a tree of method
calls, with timing information. I have found this useful in the past to
investigate a performance problem. But it might not help if the problem
only occurs at 165 queries per second (is that true?).

Hello,
In addition to the following settings, we have tried to :
- force Jetty to use more threads
- put the same GC options as our Tomcat
- change nb of acceptors and selectors
and every time Jetty is slower than Tomcat.
Any advice is welcome
Thanks,

Hello,
We are migrating our platform
from
- Solr 5.4.1 hosted by a Tomcat
to
- Solr 5.4.1 standalone (hosted by Jetty)
=> Jetty is 15% slower than Tomcat in the same conditions.
Here are details about the benchmarks :
Context :
- Index with 9 000 000 documents
- Gatling launch queries extracted from the real traffic
- Server : R410 with 16 virtual CPU and 96G mem
Results with 20 clients in // during 10 minutes:
For Tomcat :
- 165 Queries per seconds
- 120ms mean response time
For Jetty :
- 139 Queries per seconds
- 142ms mean response time
We have checked :
- the load of the server => same
- the io wait => same
- the memory used in the JVM => same
- JVM GC settings => same
For us, it's a blocker for the migration.
Is it a known issue ? (I found that :
http://www.asjava.com/jetty/jetty-vs-tomcat-performance-comparison/)
How can we improve the performance of Jetty ? (We have already
followed
http://www.eclipse.org/jetty/documentation/9.2.21.v20170120/optimizing.html
recommendation)
Many thanks,
