Hello, Developers!
1. What are the premises to use either
apache.coyote.http11.Http11NioProtocol or
org.apache.coyote.http11.Http11NioProtocol connectors?
Eh? Is that what you really mean?
i mean what are the reasons to use either connector variant.
NIO can handle more concurrent connections.
yeah, that's why i use the nio connector.
2. Do i get any advantages if i use Sync Servlet Api with
Http11NioProtocol connector or do i have to use Async Servlet Api
to get
the advantages?
What advantages are you looking for? How much traffic are you
expecting
to handle?
a lot of. i'm looking for advantages in throughput and performance, for
example.
How much is a lot?
10'000/sec
How many Tomcats are you running?
1
How much RAM/CPU per server etc?
8GB/Xeon
Only 1 CPU?
yes, but it's multicore.
How big is the average response?
300Kb
So you want to send 300k * 10000 / sec? Isn't that just under 3Gb per
second?
actually when i measured it was less than 1Gb/sec
3. How do i choose which one to use in any particular case?
First, don't prematurely optimise. Have you tested your application
yet?
yes, i need a better throughput and performance.
Please provide details.
How have you optimised your application so far, or are you hoping to
optimise Tomcat first?
webapp is optimized, i want to optimize tomcat.
How did you optimise your webapp for 3Gb/sec with only 8Gb of RAM?
i wrote nice code. it's serving 1Gb/sec with 8Gb of RAM. are you surprised?
In 3 seconds you'll have produced more data than you have RAM, how have
you optimised the garbage collector for this?
we use a custom garbage collector.
