Log buffering
 

Correct me if I'm wrong, but I have not found that feature, and it's very useful, especially on VMs.

Simple log buffer (if enabled) which is flushed to disk after reaching certain size. That's all. One option in configuration - buffer size (0=disable).

LiteSpeed already did that when server is busy. To minimize delay, the log buffer is flushed every second.

Maybe then you can add config option to flush it after it reaches certain size, f.e. 1MB
