max-threads Alanı

Bu alanın varsayılan değeri eskiden 200 idi. Açıklaması şöyle

Starting with Boot 2.3, the property has changed to:

server.tomcat.threads.max=250

Bu alan şu anlama gelir. tomcat 200 taneye kadar thread açabilir. Yani aynı anda 200 tane istek işlenebilir. Daha fazla gelirse, yeni gelenler beklemek zorunda kalır. Açıklaması şöyle

Now, if the 201st request came through, it will simply wait, till some thread is free to process the request. Here we hit a ceiling.

Örnek

Şöyle yaparız.

server.tomcat.max-threads= 8

Örnek

application.yml ile şöyle yaparız

server:
  tomcat:
    max-threads: 15

Örnek

Şöyle yaparız. En az 10, en fazla 100 thread yaratır. Eğer tüm thread'ler meşgul iseen fazla 100 tane isteği kuyrukta bekletir.

server.tomcat.max-threads=100
server.tomcat.min-spare-threads=10
server.tomcat.accept-count=100
