default MAXBSIZE is 128kB. badly low for todays magnetic disks. i have it set to 2MB on all computers that have magnetic disks. Great improvement with large files. especially when more than one are read/wrote in parallel. And no problems experienced But for optimal performance MAXBSIZE should be transfered in few times longer than average seek time. todays disk do 200-250MB/s so 2MB is transfered below 10ms. 8-16MB seems like good choice. is there any reason not to set it that high?
