What is the most efficient log viewer?

Question

System administration

I worked with both Notepad++ and Advanced Log Viewer, looked at the rest. However, I didn't find a good one. What is good in my opinion?

• opens quickly and does not slow down when scrolling over 100 Mb files
  
• manages to highlight the simplest constructions, by keywords. You can set your own keywords
  
• You can conveniently compare two or three logs recorded at the same time
  

Is there happiness in life?
Platform: Windows.

Answer 1

cygwin + less can (1) and (2), and (2) I somehow especially like it, any regexp rolls and then runs back and forth through the searched words in the log with highlight :)
Well, you can and should probably compare with tools comparisons, nothing else, the same windiff, araxis merge, etc., but the comparison is already more expensive, I won’t say anything about slowness here.

Answer 2

FAR is good. Very quickly opens and scrolls through files of any size, does not block the log and displays changes almost in real-time.

Answer 3

I'll raise a question. Maybe something happened during this time?
