Hello. Excuse me, I failed to provide basic stuff.

What version of ProGet you are running?

• It's 2025.17 (Build 12).

Is your config.toml configured to proxy all cargo requests through ProGet (overriding [source.crates-io])?

• Yes

[source.crates-io]
replace-with = "cds_registry"

[registries.cds_registry]
index = "sparse+http://serverhost.example.com:8624/cargo/public-cargo/"
#Seems to be needed even though we allow anonymous access
token = ""

[registry]
default = "cds_registry"
global-credential-providers = ["cargo:token"]

[net]
#network retries
retry = 10
#tells cargo to use git when fetching from the registry instead of the cargo default libgit2
git-fetch-with-cli = true

git-fetch-with-cli = false made no difference.

I also used the default config.toml config and it was the same thing:

[registries]
proget = {index = "sparse+http://serverhost.example.com:8624/cargo/public-cargo/" }

[registry]
default = "proget"

[source]
[source.proget]
registry = "sparse+http://serverhost.example.com:8624/cargo/public-cargo/"
[source.crates-io]
replace-with = "proget"

Do you have connector package caching and/or metadata caching enabled?

• I have Connector Crate Caching enabled, with a cache size of 38 MB. No retention policy
  (However if I check what the total size we downloaded during cargo build it's 856 MB)
• Metadata caching was not enabled (Enabling this did not make a difference)

Are you using SQL Server or PostgreSQL (the embedded database, InedoDB, etc..)?

• We installed using docker so i'm guessing InedoDB? Checking proget-database under /home/ I can see postgresql

Is it also possible to get a list of your HTTP requests and timings made during these? I don't need the response body, but the URL Path (host and feed names can be anonymized), response time taken, and response code is all I really need. In ProGet 2025, you can enable HTTP Request Logging to obtain these.

We also get alot of timeouts after having a clean slate.

Hello.

We have currently two package mirrors on the same server running, trying to replace one, and evaluating ProGet as that's the one we wanna switch to.

When doing a cargo build with these dependencies:

[dependencies]
anyhow = "*"
bollard = "0.19"
blake3 = "^1.5"
clap =  { version = "=4.5.32", features = ["wrap_help"] }
macaddr = { version = "1.0", features = ["serde_std"] }
optional_struct = { version = "0.5" }
regex-lite = { version = "0.1.6" }
tokio = { version = "1.37.0", features = ["rt-multi-thread", "macros", "net", "sync", "io-util", "time", "fs"] }
serde = { version = "*", features = ["derive"] }
serde_json = "1.0"
tracing = "0.1"
tracing-subscriber = { version = "0.3", features = ["env-filter"] }
tracing-journald = { version = "0.3"}
nix = "*"

We get a very slow fetching of packages. To compare: we counted seconds for a build to complete for each, you and artifactory. Both with cache cleared
Proget : 88s
Artifactory : 15s

We are not familiar with ProGet so I wish for some help regarding why these numbers are so far apart, we are on the trial license currently.
