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! :)
