memsharded: Would also love to have the feedback of @claasd, IIRC, you had big dependency graphs and using version ranges too, so this fix might be good for you too.
claasd: Hi,

we completely change from version ranges to aliases once they became available. So sorry, can't help you here. We are quite happy with the alias feature, where we for example use OpenSSL/1.1.0 as alias for OpenSSL/1.1.0i, or MyPkg/1.0.latest as alias for MyPkg/1.0.2.

Best,
Claas
memsharded: Sounds good, thanks for the feedback @claasd !

Enhance graph dependency resolution speed
Hello,

I have a big dependency graph that is managed in our CI system. About a hundred packages are handled and depends on each other by using version range like `[^1.66.0]` to keep, according to semver, the last backward compatible package.

The fact is that as all packages requirements are expressed that way.
I observed that conan, for each package, make a query to resolve the range and that can take a lot of time.

Observed times are with conan <= 1.4 a `conan info . -bo ... -bo ... [...]` on the graph would take about fifteen minutes (depending on the number of `-bo` that are passed).
On conan 1.6, it is twice as before.

As a way to enhance the resolution, can conan create a cache so they are resolved only once and future calls to the same range will be answered quickly ?
