It's what I am going to do, but it seemed strange to repeat the syswrite N times, one for each data chunk. I was just wandering if there's a "safe" way to concatenate data (meaning: does the "." operator change the buffers or not?) and then issue just one write (writing a larger chunk should should also optimize I/O).
Another interesting question: is it faster to concat data and then write once, or is it faster to issue one syswrite for each buffer?
I'm afraid I'll have no time to benchmark.
