Hi, I am Duminda Rathnayaka. I live in Sri Lanka. My nick means Old man in English which is also my DotA alias. I play in Garena in SL room. I like to learn and I have worked with C++ and know a little Common LISP. Well, that's about it for now. I'll edit this if I feel like it later :D.

and the perceived latency or slowness could be due to I/O being tied up within the kernel/OS before it even reaches the disks : How to figure out if this is the case?

Ran your program. In the old system it takes 10.157 seconds while in the new one it takes 0.082 seconds! So, does this mean this is a GLOG problem?
