When that is done you need to setup a RAM-Drive, find out in your file explorer how big the installation for lazarus including fpc is and set the RAM-Drive to that ammount + 1GB extra.
Given how well Unix uses its disk buffers, I doubt that would have much benefit to be honest. Its already Nvme2 and while compiling does trigger some "device contention", not much, its just about "RAM" anyway.  Unless, as TRon mentioned, the hardware setup is less than optimal. Thats unlikely with a box setup with 16G ram.

vfclists - can you give us your definition of "slow" - how long to Build so many lines of code ?

Last time I did such for myself was on Windows Vista (yes I had [hate] it... puke) with a mechanical HDD and a bloated up Delphi installation.
With a few tricks I've set up a 64bit Ramdrive that was able to use my current Delphi.
Startup speed: from about "i go make a coffee" drained to "look out of window and back on monitor" - done
Compilation speed: from 3 minutes down to less than 3 seconds
So yes, I was happy at that time :D

Since my experience with non-Windows is like 0, you guys know what you talk about, I just can tell about my experience.

Use "-vi" switch and watch in message window what the compiler tell you.

Yes, back in the days when I used Windows, ram disks were always a good idea. But that was Windows2000 for me.

I am still amazed how long it takes to unzip the Lazarus source on Windows compared to exactly the same hardware running Linux. (Like, 5 times as long ?) But truth is, Linux lies to you, it says "yep, I have that, next ?" but it is still writing, behind the scenes, to disk.

Is it "-vi" of "-vl"?

I see "-vl" Show line numbers but I can't see -vi anywhere.

Is it entered manually somewhere?

I from Isaac (but not capitalized)

Not every command line option is visually present.

For information about -vi see Alphabetical listing of command line options

Quote
-v<x>  Be verbose. <x> is a combination of the following letters: 
      i : Show general info

Yes. either in compiler options or in a build mode override (if you use build modes)

I've set it, but I can't see where the lines compiled is displayed.

How do you run the compilation from the command line, ie find out the command used to compile, then run it in a terminal?

Compile/Build with Lazarus once and than do a right click in messages window.
See attachment.

In the message window, but by default (some type of) messages are filtered (depends on your settings).

And i have to correct myself. You can use the -vi option but I just noticed here you can checkmark the "show FPC message: lines compiled)" (I did not know this one but assume that means the number of lines compiled as shown when using -vi ?)

When you want to compile a Lazarus project the easiest is to use lazbuild and provide the Lazarus project filename that you wish to compile as an argument.

My thinking, because I activate many times "-vd" switch that the LOC are included since in the message options LOC is disabled.

I repeat-

$> wc -l *.pas

(Open a terminal window, go to source dir and type that command, 'wc' space dash lowercase L )

Is wc -l *.pas recursive?

Anyway after saving and examining the messages.txt (which for some reason has the executable bit set) I will be able to work out which files are compiled and do a line count on each of them.

Does Lazarus have a way of prefixing the Messages entries with timestamps?

No, would require some clever "find' commands if your code is in multiple directories.   :(

How about telling us how long it takes anyway ?

A very useful tool to "measure" the source code metrics is sloccount. It is claimed to support also the Pascal syntax:

https://dwheeler.com/sloccount/


In recent debians is natively available for apt installation.
FPC 3.2.0/Lazarus 2.0.10+dfsg-4+b2 on Debian 11.5
FPC 3.2.2/Lazarus 2.2.0 on Windows 10 Pro 21H2
