"Samples/15 - External DB performance/PerfTestConsole.dpr" new project
This new sample will be the new cross-platform and cross-compiler way to benchmark and validate our ORM with external data.
Some preliminary tests on Ubuntu, with our brand new SynDBPostgres unit:
Running tests using Synopse mORMot framework 1.18.5887, compiled with Free Pascal 3.1.1 64 bit, against SQLite 3.31.0, on Ubuntu 18.04.4 LTS - Linux 5.3.0-42-generic, at 2020-03-24 16:48:46.

@ab -this is VM or host? What CPU? Can you run a pgbench just to have a relative numbers
// once for initialization
// pgbench postgresql://postgres:postgres@localhost:5432 -i
// and then test selection speed
// for prepared stmt
pgbench postgresql://postgres:postgres@localhost:5432 -c 4 -M prepared -T 4 -S
// and without prepare
pgbench postgresql://postgres:postgres@localhost:5432 -c 4 -M simple -T 4 -SI fight 2-n day long with hosting where I rent a 12-Core-XeonE5 server for test. The shits they give me works 3 times slower when my laptop (I think they have problems with hypervosor)

Small fix (@ab - it strange how you can compile w/o this changes on FPC/Linux, at last I got an error) https://github.com/synopse/mORMot/pull/294
Please, add a reference PerfTestConsole.ini file into git just to know what t wrote there 
There is AV in case ini file if missing (actually when PG password is wrong

All available tests: https://gist.github.com/synopse/53601e7 … a4e771d270
(please do not put numbers in the forum thread, but use gists as I did)
@mpv
I think I have corrected now what was missing.

Re: "Samples/15 - External DB performance/PerfTestConsole.dpr" new project
My previous benchmarks were with logs enabled.
A lot of logs in fact - around 100MB.
Here are the new numbers with logs disabled:
https://gist.github.com/synopse/d2be310 … ea34f5bf1e
In practice, numbers are almost the same.
Meaning that a log of log doesn't impact the business... good to know!
Worth noting that AES encryption has almost no impact about performance.
Thanks to our AES-NI hardware accelerated SynCrypto library, for sure!
Note that I have a very fast SSD (3GB/s burst).
