XSMeXtended Sort Merge

Windows and AIX benchmarks: comparing XSM with standard sort utilities and tracking performance across versions.

Testimonials

Thank you for allowing me to evaluate your excellent product. In terms of performance it was clearly the best product available on the market. I bench-tested it against a number of other sort utilities and it performed at a minimum of 2.5x the speed of the other programs.

I am therefore in a position to recognise high quality, and your software is amazing.

Over ten years, Base Plus moved from Small Data to Big Data. XSM is the only software that has supported us from the beginning: from a few million records, we now sort files containing more than one billion lines, still with consistently astounding performance.

XSM benchmarks

XSM 7.00 and native Windows sort elapsed times for files from 1 to 20 GB — Median elapsed times for sorting 1, 5, 10 and 20 GB files.
XSM 7.00 is **4.71 to 9.48 times faster** than native Windows sort in these measurements.

XSM 6.71 to 7.00 elapsed-time evolution on Windows for 1, 5 and 20 GB files — Comparison of XSM versions 6.71, 6.93, 6.94, 6.95 and 7.00 on Windows using 1, 5 and 20 GB files.
The displayed times are measured median elapsed times in seconds.

All benchmarks follow the same protocol: files generated with sortgen, one unmeasured preliminary pass to neutralize cache effects, identical input, output and sortworks disks, followed by median elapsed times measured over three runs.
