Of course it’s worth testing. Optimised or not (and I suspect that aspect of zcashd is in decent shape), it still allows for comparison of different systems. [https://benchmark.minezcash.com/](https://benchmark.minezcash.com/) ---

Hey @voluntary, great work on setting up the wiki table for performance! I’d recommend putting filters on the columns, so that we can order descending/ascending by equihash-10, for example. Wish I could help, but busy right now. Will take a look later if you haven’t already solved it! Cheers, tom ---

Please feel free to have a look and see what you can do. Wikimedia has code for the tables that is tricky to use so I have been having people use the table generator and copy/paste the results. Unfortunately that doesn’t really have advanced table functions like sort/filter. If you have a better method I would l be happy to use it. ---

It’s `genproclimit`, not `procgenlimit`. ---

The ‘10’ parameter you entered is for the number of consecutive times the equihash benchmark executes. There’s an optional second parameter for specifying the number of CPUs / cores but I don’t know if it’s actually implemented yet… ---

Do you mean the parameter “genproclimit”, I have set up this parameters, it works well. ---

Hi, @Shawn, I finally got round to doing this. I thought it would be a pain, but it was laughably simple 😀! All I had to do was change it from `class="wikitable"` to `class="wikitable sortable"` and it automagically did what I wanted! Now you can sort the tables by column, which makes it much easier to see what performs best and worst. The method of entering data etc. (in fact, nothing else) has changed! ---

@foodforthought Nice find! I didn’t even know about the different classes of tables, this will help a lot 😆 ---

Have made some modifications to the table; hope that’s cool with you? Have added RAM per core, and made the numerical numbers sortable as numbers, rather than strings. I’m not sure everyone’s following the same formula for calculating hashrate/core, though 😆! ---

Yeah, I’m not sure we can use the H/s formula for a huge Cloud instance. Maybe we need to have a separate chart for clouds since you are using so many separate processors it’s probably not possible to accurately measure single core performance, nor is it possible to know the precise memory configuration. So it would only need the average time column, num. CPU’s, memory amount, and maybe a cost?
