Tuning LiteSpeed using memory mapped to serve < 4MB static files

[redstrike]

I have a 768 MB VPS, it is free 1/2 of total RAM. Is it ok if i tuning LiteSpeed to handle static files which < 4MB, by using MMP?

Max MMAP File Size (bytes): 4M 
Total MMAP Cache Size (bytes): 256M

My site is still running OK. But i don't know is there any drawback if set Tuning Settings like that?

serving files which has 16KB from the memory buffer cache is optimal than 4KB???

Is there anyone can give me an advice? Using MMP or sendfile to serve large static files like audio, video is the optimal solution for reducing disk I/O?

to serve large static files, sendfile is better
