What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

What is LibreSpeed?

LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.

LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.

Dragonfly vs LibreSpeed: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.

LibreSpeed

2.5

LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.

◆ Current state

LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.

◆ Where it's heading

With the design migration done, releases focus on measurement accuracy and easier Docker deployment. Minor versions arrive every month or two.

◆ Prediction

Expect further accuracy and deployment fixes in 6.3.x; no larger feature is signalled.
