Xavier Hanin commented on IVY-551:
----------------------------------
Ivy has not been really designed for multi threading, but I know that it is
used in multi threaded environment at least in IvyDE. Since it isn't designed
for that it may be the cause of some problems, but using only one buffer would
be the source of a lot of problems in this case I think.
What could be done is to use one buffer per thread (using a thread local). But
I don't know if it will really improve performance. We would need time for
testing, and I haven't enough time for the moment. But if you have some, using
a thread local buffer shouldn't be too difficult to implement, so feel free to
give it a try, run some benchmark and report your results.
> File buffer should be increased to 64KB

> File copy is slow because the buffer is too small. Increasing file buffer
> should alleviate the problem while NIO should be explored as well.
