Hi,
Using a small test file (~550 MB) on my machine (2x Xeon(R) CPU
E5-2670 with RAID6 SAS disks and 192GB of RAM), the D version
runs in about 20 seconds and the Python version less than 16
seconds. I've repeated runs at least thrice when testing. This
holds true even if the D version is compiled with -O.
Sounds like this program is actually IO bound. In that case I
would not expect a really expect an improvement by using D. What
is the CPU usage like when you run this program?
Also which dmd version are you using. I think there were some
performance improvements for file reading in the latest version
(2.068)
