I'm running Mint Xfce on a 2010 Sony Vaio, and it handles light tasks reasonably well. The laptop has 8GB of RAM, so memory isn't really the problem, but booting is slow and some applications take a while to open. Would Puppy Linux be a good way to improve performance because it can run largely from RAM? I assume I'd also want a lightweight browser for everyday web use.
I've read that Puppy can save settings and installed changes back to a live USB, but I'm unsure how reliable or convenient that is. There are several Puppy variants too—would a Debian-based version be a sensible choice, or do the differences matter much for this use case?
I'm also considering installing an inexpensive SSD, cleaning dust from the laptop, and replacing the CPU thermal paste. I've never done much laptop disassembly beyond upgrading RAM, and this model looks fairly cramped inside, so I'm treating it as a low-stakes project to learn more about Linux and hardware.

Puppy’s main advantage is loading much of the system into RAM, but the different Puppy variants can vary quite a bit in package availability and hardware support. EasyOS is worth considering because it also runs from RAM by default, has persistence enabled during setup, and generally offers broader package support. MiniOS is another similar option, though installing additional programs as RAM-loaded modules is a little less straightforward.
If you mainly want a responsive, conventional desktop rather than a specialized RAM-based setup, try antiX, Q4OS with the Trinity desktop, or MX Linux Xfce. With 8GB of RAM, your current Mint Xfce installation may already be fine once the storage bottleneck is addressed. Testing a few systems from USB before installing is the safest approach.
If the laptop is still using a mechanical hard drive, replacing it with an SSD will probably make a much bigger difference than switching distributions. An older laptop with an SSD can feel surprisingly quick, even when running a relatively full desktop such as Mint Cinnamon. Booting, launching applications, and general system responsiveness should all improve.
An SSD is definitely on my list. I’ve only opened a laptop once to upgrade the RAM, so I’m a little hesitant about taking this one apart, but it seems like a worthwhile project for learning.

Q4OS unfortunately gave me trouble when I tried to replace Mint Xfce, and the installation failed even though the existing partition and desktop were still intact. I’m not sure whether the USB creation tool or something else caused it. I’ll still give antiX and MX Xfce another look, especially since my previous antiX experience was on an older netbook with difficult Wi-Fi support.
