I sent my programs / database to Yard last wednesday. they did some testing on their version (FreeBSD 2.1.6) It worked really fine except for a few slow down. (for him 350 seconds on a pentium 133) For me on 3.0-980594-SNAP and FreeBSD-2.2.5-STABLE it's still unusable (I stopped the program after 25 minutes on a Pentium II 333). We are writing some application that we are planning to bundle with the Yard SQL engine. I can't imagine that I would have to tell my clients that to run our applications they have to install the FreeBSD source code and modify the kernel and rebuild it. do you have any idea on how we could definitively solve this problem for 2.2.X and 3.X versions of FreeBSD ? -- Didier Derny didier@omnix.net ---------- Forwarded message ---------- I ran your program on our system and it shows a similar behaviour as you describe. Below is the vmstat output, which indicates the hanging moments with an idle time of > 50%. But these moments don't seem to be that awful. In total your program took 350 seconds on a 133 MHz Pentium. If the reason for this behaviour is in fact the 100 byte problem mentioned by one the FreeBSD guys, the only possible way to solve it would be to set ack_delayed=1 (in the kernel?). Anything we at YARD can do?
