调研方向

从日志读取器的显示过滤流程开始，使用 warning、error 和 fatal 级别在 Nextcloud 34.0.4 上重现该问题。比较初始的过滤加载与未过滤加载之后的过滤，并调查自动刷新路径。当过滤后的日志能在约一秒内加载完成且没有明显的 CPU 峰值，并且自动刷新恢复工作时，即视为完成。

Steps to reproduce

Use Nextcloud 34.0.4
Go to log reader in admin settings
Set "Filter logging levels" to only display warning, error, fatal (backend log is set to the same settings by default)
refresh the reader
loads for more than 10 seconds

When the filtering is applied after initial load (without any filtering) the filtering happens instantly.
Before we used Nextcloud 32.0.8 - the problem did not exist there.

Expected behaviour

Logs typically load within one second
No notable CPU spike
Logs refresh automatically

Actual behaviour

Logs take upwards of 10 seconds to load
Extreme CPU usage (in kubernetes from 0.1 CPU to 3.0 CPU)
The automatic refresh does not work anymore
