Java Performance in Containers
Performance Tuning of the JVM inside Containers
We'd like to learn your experience with running and tuning JVM-based microservices inside containers.
OK
*
1.
Do you deploy JVM-based microservices inside containers?
(Required.)
Yes
No
2.
How best would you characterize the majority of these microservices?
CPU intensive (e.g. 3D rendering, financial, scientific models, machine learning models, audio/video processing, data mining)
Memory intensive (e.g. big data analysis, in-memory data grids)
I/O intensive (e.g. file processing, network calls)
I don't know
*
3.
Do you give a limit of CPUs to the containers?
(Required.)
Yes
No
*
4.
If you do provide CPU limits, how many CPUs on average do you limit your containers to?
(Required.)
1 CPU
2 CPUs
3 CPUs
4 CPUs
8 CPUs
More than 8 CPUs
I do not limit CPUs on my containers
Other (please specify)
*
5.
Do you give a limit of Memory to the containers?
(Required.)
Yes
No
*
6.
If you do provide Memory limits to the container, how much memory on average do you limit them to?
(Required.)
64 MB
128 MB
256 MB
512 MB
1 GB
2 GB
4 GB
8 GB
16 GB
32 GB
I do not limit RAM for the containers
Other amount (please specify MB/GB/TB)
*
7.
Do you adjust the JVM Heap Size to better fit in the container?
(Required.)
No
Yes, with -Xmx
Yes, with -XX:MaxRAMPercentage
Yes, with a different flag (please comment)
*
8.
Do you know which Garbage Collector is ultimately used by the JVM on your microservices?
(Required.)
Yes, all of them
Yes, most of them
Yes, some of them
No, none of them
*
9.
Which Garbage Collector are your workloads described above using the most?
(Required.)
SerialGC
ParallelGC
ParallelOldGC
CMS
G1GC
ZGC
Shenandoah GC
Zing C4
Epsilon GC
I do not know
Other (please specify)
10.
JVM Ergonomics: If you do NOT explicitly select a Garbage Collector, how satisfied are you with the JVM Ergonomics for the workloads described above?
Very satisfied
Satisfied
Neither satisfied nor dissatisfied
Dissatisfied
Very dissatisfied
11.
GC Tuning: If you DO explicitly select a specific Garbage Collector for your workloads, or you know which one is in use, how are you satisfied with this garbage collector?
Very satisfied
Satisfied
Neither satisfied nor dissatisfied
Dissatisfied
Very dissatisfied
*
12.
GC Tuning: Do you know if a specific value for GC Threads is provided?
(Required.)
Yes, GC Threads is manually tuned.
No, GC Threads is not manually tuned.
I do not know
I do not specify a GC
13.
Could you provide more insights into what most of your microservices are doing on average and how are they implemented (choice of framework, Java version, etc)
14.
Would you like to be contacted by the Microsoft Java Engineering Group for an in-depth discussion on this topic and share your experience and feedback?
