Summary0002267: Application slow when debugger is not running VS Code

I just upgraded PHP from 7.4 to 8.3 and applications are running so much slower. My problem seems nearly identical to the previous defect

I also get many (>20) repeated messages in the xdebug log of the form:
[15600] [Step Debug] ERR: Time-out connecting to debugging client, waited: 200 ms. Tried: localhost:9003 (through xdebug.client_host/xdebug.client_port).
[15600] [Step Debug] INFO: Connecting to configured address/port: localhost:9003.

In my case, I'm making the request to PHP from my regression tests. I know each of the requests made to PHP, there are only two:

[17/May/2024:17:50:27 +0000] - "POST /api/authenticatev3 HTTP/1.1" 200 123 "-"
[17/May/2024:17:50:41 +0000] - "DELETE /api/user/users? HTTP/1.1" 403 58 "-"

Any advice would be appreciated!


zend_extension = "C:\www\php8\ext\php_xdebug-3.3.2-8.3-vs16-x86_64.dll"

xdebug.client_port = 9003

xdebug.log = "c:\www\Apache2.4\logs\xdebug.log"

My PHP code initializes the AWS DynamoDB API to manage session information. If I disable the call to DynamoDB, the multiple timeouts go away.

This is a regression from my PHP 7 setup. Any suggestions on how to improve performance?

The error message "ERR: Time-out connecting to debugging client, waited: 200 ms. " indicates that your network stack doesn't immediately reject the connection if it can't be made. That's usually due to a (misconfigured) firewall.

Can you check that?

Unlike in 0002076, I can't ask you to strace, as Windows doesn't support that.

Not enough feedback provided, and can't reproduce this myself.
