It's a tradeoff. We can reduce the dynamic allocation, by simply reusing the qstring instead of allocation a new one (after complete/partial write). At the cost of wasting some memory. Given that qstrings grow expotentially I think the dynamic allocation overhead isn't that bad. > Instead, how about sacrifice > some time to wait output complete, since monitor is not time critical? The watch added recently will fire when there is space for writing. Right now it will write out the next chunk from the buffer. In theory we could change the monitor code to continue generating the response when there is more output space, so we don't have to buffer it in the first place. But I think the complexity simply isn't worth it for the memory savings we can gain. cheers, Gerd
