I am not aware of any such bias with Firebird but it certainly can exist with other software.

Intel provides what I am told is an excellent compiler - which they provide for free - and many software companies utilize it.  That compiler has long been known to generate executables that are crippled when run on non-Intel CPU's.  There have been a quantity of reports, possibly some legal action, and I don't know that anything has changed.

However - I believe the binaries provided for Firebird are not generated by that compiler so it's not an issue.  In your case, based on your description, you have similar systems with similar drives so unless there was *significant* calculations required I'm not surprised you have similar performance.

Hello all,

I ran an update query on a database with a computer and a notebook.

CPU's computer is Phenom 1075T, while notebook is i5 2557M.

Query is very simple, something like : update tbl set ln = 9;

Firebird  on Computer is SS 3.0.3, on notebook SS 3.0.2, both runs on Windows x64, both using SSD with roughly, same speed.

I thought, query will runs much faster on a computer, but to my surprise, it runs almost the same time on both machine.

Query runs in a single thread, on computer, runs around 3-3.5GHz, on notebook, runs about 2.7GHz.

I am planning to upgrade my computer to ryzen, but with this result, make me wonder if  Firebird favor intel's cpu.

Regards,
Anto
