Upgrading HAProxy 2.0.13 to 2.4.10 (Ubuntu 20.04) -- performance & issues?

tr flag

My company is currently using HAProxy 2.0.13 (from Ubuntu repository).

Since latest HAProxy (just released last month) is 2.5, we think HAProxy 2.0.13 is a bit "long in the tooth". Also, (claimed) performance improvements of 2.1 seems to be a 'nice to have'.

But due to the 'newness' of 2.5, it's not yet available in HAProxy's ppa; but the latest in the 2.4 line (i.e., 2.4.10) is available. So we figure we're going to upgrade to 2.4.10 instead.

My questions:

  • Is it true that HAProxy 2.1 (and by extension 2.4.10) has better performance than 2.0?
  • Is there any 'gotchas' I need to be aware of upgrading from 2.0 to 2.4?

my suggestion is, backup and create a snapshot and give a shot.

Capacity planning and load testing don't translate well to other hardware, use cases and environment. As djdomi said, give it a whirl and see how it goes for you. In any case, 2.0.13 is long overdue, the latest 2.0 is 2.0.26 so you should consider upgrading. If not to 2.4 then to the latest 2.0.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
