What is the writing speed on local storage of MBED LPC11U24 in bytes/sec?

Considering the mbed LPC11U24 micro-controller :-

1. What is the writing speed of fprintf() function on local storage in bytes/sec?

2. What time it takes from fopen() to fclose() with reference to your LocalFileSystem_HelloWorld - main.cpp program?

3. Is there any other delay in opening, writing and closing the file?

I've been getting around 2200 bps reading from the LFS. not exactly what your after but what is everyone else experience here?

update: I wrote a test program that writes 252 bytes to a file in 3.852 seconds. Still not blazing fast but faster than your 10 bytes/sec.

Thank you. But I want to know the writing speed which is very low in my case. Approximately 10bytes/sec.

I would like to see your test program that writes 252 bytes to a file in 3.852 seconds on LocalFileStorage. Which Mbed device you are using for this test program.
