What problem does this PR solve?

Issue Number: close #xxx

Related PR: #xxx

Problem Summary:

  1. In high-concurrency stream load scenarios, there aren't enough webserver threads available.
  2. During stream load, after data reception and while waiting for execution, the synchronous wait occupies HTTP threads.

To address the issue of insufficient HTTP threads during high-concurrency stream loads causing slow data reception, we increased the number of threads.

[opt](load) Increase the default value of webserver_num_workers (#46304)

1. In high-concurrency stream load scenarios, there aren't enough
webserver threads available.
2. During stream load, after data reception and while waiting for
execution, the synchronous wait occupies HTTP threads.

To address the issue of insufficient HTTP threads during
high-concurrency stream loads causing slow data reception, we increased
the number of threads.
