Is there a preferred EC plugin?
Hi, we currently use the jerasure plugin, but maybe there is a new better default? We use EC mostly for large rgw data with files >1GB. Cheers Boris

Yes, ISA-L is proposed to become the new default. See [1] and [2]. There are also a lot of EC improvements (coming) in new(er) releases [3].

Thanks :) Now I try to find a way to transit to the new engine. Probably by creating a new pool and copying over the data. Am Mi., 3. Sept. 2025 um 14:32 Uhr schrieb Stefan Kooman <stefan@bit.nl>:

Is there an estimated release when we might see the EC high performance changes available on Squid 19 (or 20)? On Thu, Sep 4, 2025 at 6:34 AM Boris <bb@kervyn.de> wrote:
