Downloading jar files from JNLP using open web start plugin takes longer than Oracle JRE

[channareddyp]

Hi Team,

Issue: Downloading jar files from JNLP using open web start plugin takes longer than Oracle JRE, it is taking 3 to 5 minutes in same subnetwork, network speed also good.

Adapt Open JDK Version: Java Runtime Environment version 11.0.19
Open Web Start Version : 1.7.0

Client to Server Ping test: 127 ms
Server to Client Ping Test : 127 ms
Client to Server latency Test: 100 ms

Same issue happening with IceTea-Web as well.
Adapt Open JDK Version : Java Runtime Environment version 8 update 312
IcedTea-Web Version : 1.8.8

But Oracle 1.8, it is opening in quickly 30 seconds.
Attaching open JDK debug log file for reference.

Its a high priority issue for us. Our end customer is escalating this issue and hence any quick solutions/suggestions would be highly appreciated.

We have issue replicated locally, we can have web-ex and verify.

Thanks
Channa

Hi Marc,

We have tested on Open Web Start Version 1.8.0 as well, but still taking 3+ minutes to download jars and launch java console.
Please suggest and help.

don't have this issue, debug and use a profiler to check the bottleneck

do you use a proxy

[channareddyp]

No, we are not using proxy.

Enabled client debug and verified the logs, the delay happening while downloading the jars.
Any fix plan this issue in future release ?
