Getting back data from stream is about 80x slower than sending...

Dear people,

I am using SDK1.4 with Brook+ to do integer matrix operations. In my application I see that using stream.write is 80x slower than using stream.read for the same amount of data. Is that normal? Is there something that I can do to have the same performance in both operations? Thanks in advance for any insight to this.

best regards,

Alfonso
