I could see from the documentation that the default was 4k, not the max.

About the cpu performance, i get mirc to use 40% cpu on a dual core 2.6GHz.
It make more then 45 read each second and maxs at 50 read second making a total of 200kB/s.

When i send data i can make up to 250 sends of 8k (2MB/s)
Case you wounder this addon is a web server, and yes, it doesn't work bad smile

It is not bad, but if i could read 8k each time...
But is there is no chance, it is ok.

Thanks
Best Regards
