This must be good news for some, and the FPC project. :-)

Sometime ago, there was a brief mention of multi-threading FPC would be
counter productive because compilation process was mostly disk IO bound
--this is what I understood anyway.
I wanted to check to see if disk IO was really limiting FPC/Lazarus
compile performance.
The only quick way I

This doesn't make sense. FPC/Lazarus compiles on the faster medium
longer (albeit only 3 sec.).
Everything on your SSD is cached in RAM, so it's normal that both are
about the same

I am sorry, but what you've just said

In our previous episode, Adem said:

The only quick way I could devise to check this was to use two different
disks which are significantly different from one another in terms of
performance.
Both are
AFAIR the ATTO tool measures read and write bursts of single files X in size.
An interesting exercise is to transfer 1000 files to a USB memory
stick in 2 situations:
- Compacted in a single file, transfers at or near full USB speed.
- Spread out normally on a folder takes forever.
This happens

This happens because the time it takes to SWITCH between one file to
another is significant. Ending one operation (a single file transfer)
and begining another takes a time slice. Summing up all these start
and finish ops takes a significant time slice.
