Hi everyone, for this blog i am going to attempt or figure out a way to optimize the code in the Zopli program.After profiling in stage 2 i found out that the function that was taking up the majority of the run time for the program was called ZopliUpdateHash(). Since this was taking up a bulk of the time iI decided that this function was the first thing that needed to be optimized since it would have the largest affect. This function can be found under the file named "hash.c" and looks like this. Aside from this function I did look around for other functions to see if there was anything else i could optimize. After looking for about 15 minutes I noticed that the code was well written and it well documented on the Github. If it was'nt for the documentation I probably would'nt even know what half of that code did. During this stage I had encountered a bunch of problems, Nothing I did worked for the most part. The first thing I did was change th

The link to stage 1 can be found at the bottom of this post. Like the first stage i had to do this for the AArch64 and the x86_64 architectures. The first architecture i attempted this on was a x86_64 architecture and I was a bit confused. During stage 1 and 83mb file took around 4 minutes on average to compress. After trying again today it was taking over 8 minutes. I could not figure out why this was happening and I spent quite some time on it. Defeated, I decided to just use a 43mb file instead that ended up taking the amount of time I posted on stage 1.   X86_65 So after watching the helpful video that my professor posted on the CDOT wiki, I attempted to "profile"
