The first thing to do is to check the output from dmesg on both nodes and make
sure you don't see anything like "sda: Uncorrectable error writing sector
12345678".  If you see this, it means one of your disks is dying horribly. 
This can cause delays while writing, since the kernel and disk will try to
write to that sector several times.

It's impossible to tell, since we can't see your drbd.conf.  Put that file on
your webspace somewhere, and follow up with a link.
