Payara 5 HTTPS extremely slow

Question

I've met a really strange case:

Before migrating to Payara 5.182, I use Payara 4.1.181, and the http/https requests are all very fast. Things go strange when I migrate to Payara 5.182, http requests are working just fine, but the https requests are extremely slow.

Here's the information:

• the application that deployed to Payara 5.182 / Payara 4.1.181 is the same version
• configure the keystore.jks and cacerts.jks in Payara 5.182 just the same way as Payara 4.1.181:
  • keytool -importkeystore -destkeystore keystore.jks -srckeystore 3MEdu.p12 -srcstoretype PKCS12 -alias 3medu_cert
  • keytool -importkeystore -destkeystore cacerts.jks -srckeystore 3MEdu.p12 -srcstoretype PKCS12 -alias 3medu_cert
• the 3MEdu.p12 is the same file as used in Payara 4.1.181
• use 80 port for http request and 443 port for https request
• JDK version: Oracle JDK 8u161
• OS verison: Ubuntu 16.04.4 LTS

Answer 1

Payara 4和5之间的区别是Payara 5中默认启用了HTTP / 2。请尝试按照文档中所述禁用HTTP2： https ://docs.payara.fish/documentation/payara-server/server-configuration/http /protocols.html

Answer 2

Thanks for this, the complete menu are:

Network Config -> Network Listeners -> http-listener-2 - HTTP TAG an search the HTTP/2 Option to disable
