maximum MAXBSIZE

[Wojciech Puchar]

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?
