[asad.awadia]

this is pretty cool - great work

[asad.awadia]

is http4k its own client? Or a wrapper around the apache client?

[dave]

It provides a single interface around OkHttp, Apache4/5, Jetty, or JDK clients

[dave]

Same with the server and serverless backends - you choose whichever you’re most comfortable with and just plug it in.

[asad.awadia]

Do you have any thoughts on jetty around memory usage and performance?

[dave]

Not really tbh. Personally we tend to default to undertow. Did you need web sockets?

[asad.awadia]

No - req/resp http is fine
does undertow not support WS?

[dave]

Not at the moment. Jetty and Netty only

[asad.awadia]

what are your thoughts on undertow around mem usage and performance given that its the default?

[dave]

AFAIK the only server which has higher memory consumption is Apache 4 and 5 (although they have generally the best performance according to TechEmpower. TBH we haven't really done many experiments with memory usage - although we'd be really happy to hear if anyone does any!
