Hi, all,

I just had my five-year workstation upgrade for my work laptop. Since BaseX is my main productivity tool, I was curious to test performance on the new hardware.

Old machine:

2016 MacBook Pro

2.6 GHz Quad-Core Intel Core i7

16 GB 2133 MHz LPDDR3

New machine:

2021 MacBook Pro

Apple M1 Max

32 GB unified memory

With BaseX 9.7.3 beta, I tested a 4.11 GB XML document that has a series of entry elements, each representing a name from our library catalog. On the old machine, it took 9 minutes to create a database from this file, with text and full-text indexes. On the new machine, it took 3.5 minutes.

I ran the following query on both machines:

<data>{
for tumbling window $entry in /*/entry
start $s next $sn when starts-with($sn/key, $s/key)
end $e next $en when not(starts-with($en/key, $e/key))
return
<group id="{$entry/@id}">{$entry/key}</group>
}</data>

On the old machine, execution time ranged from 40s to 47s. On the new machine, it ranged from 11.5s to 18s.

In short, it looks as though I'll be a lot more productive now! :)
