Half Height Gigabit NIC wasn't originally HH

I am an amateur homelabber at best, and I like using old parts that get the job done, especially if recycled.

This eBay special had some modifications I didn't notice until recently. It appears that it wasn't always a half height card.

For those curious, this Intel CPU-D33682 has worked flawlessly in my dell optiplex 790 with a core i5, 12GB of RAM, running OPNsense. Using this as a router, my limited 400Mbit internet connection routinely hits 500Mbit on speed test, so I am happy.

I pulled it out to dust the computer while replacing the CMOS battery, and then noticed how odd it looked.

Next you're going to tell me these AREN'T supposed to be covered in rust from the past 157,000 miles. It isn't like I bought the car without being able to get the title (now fixed) in my name from a teenager for $750.

Oh, that's rich. There's no possible way this is part of why the car barely runs, and I definitely didn't need to buy ISTA, off of eBay, to figure it out.

(But it in all seriousness, I'm just glad it's one step closer to working.)

This is my first time installing root on ZFS manually, and I am using RAIDz1 across 6 256gb SSDs. All of this is running on an ancient dell poweredge R815 that I am trying to use as a desktop, so I am looking for performance gains where available.

Yes, I know it's not the best idea to use a server, but it was free and this is fun.

Here's the question: Would including a 32gb partition on an SSD for use as a ZFS Intent Log (ZIL vDEV) actually boost write performance?

Likewise, I plan on increasing the ARC size to 50gb as the system has 256gb of DDR3, and my normal use doesn't hit 25gb. Would I see a boost in read performance there as well?

If neither would make much of a difference, I will first try this install without for simplicity.
