[Webfig/Log] Displaying logs from memory takes very long time

RouterOS General
1

Hi!
I’m using WebFig v6.37.3 (stable).
My logging is configured as follows:

Actions:

  1. disk
    Name: disk
    Type : disk
    File Name: disk1/logs/log <— I’m using external USB storage for log files
    Lines Per File: 65535
    File Count: 65535
    Stop on Full: unchecked

  2. memory
    Name: memory
    Type: memory
    Lines: 100
    Stop on Full: unchecked

Rules:

  1. Rule 1:
    Topics: !packet
    Action: memory
  2. Rule 2:
    Topics: !packet
    Action: disk

What I wanted is to log everything to disk and to memory except for “packet” messages. I expected that when I go to Log menu and set filter to “memory” I’d be able to see recent 100 lines of logs immediately from memory (moreover I set up Design Skin to show “memory” logs by default). But it seems that RouterOS scans (unnecessarily) all these thousands of logs from both memory and disk and filters out messages while scanning which is slow (especially if you expect to see just last 100 lines from “memory”).

Hope this could be improved.
