Hi, ChrisLu, Weed-FS is Great, I tested is fast:

> Requests per second:    6029.21 [#/sec] (mean)
I try use "weed filer", But tested is slow:
ab -n 10000 -c 100 http://192.168.1.1:8888/2014/05/23/1.jpg
> Requests per second:    1885.35 [#/sec] (mean)

Could you tell me why? Thank you very much.

Filer does extra work, to serve a filer request:

1) filer: lookup directory in memory, this should be very fast

2) filer: lookup file "1.jpg" via leveldb

3) filer: proxy the request to weed volume

4) Volume server returns data to filer

5) filer: give the data back to client

Just compare one single file performance is not really meaningful. Put lots and lots of files under one filer folder, and randomly access one of them. Filer can handle it with fairly consistent speed without much speed degradation. That's where the power of filer shines.
