> Key: IGNITE-1694
> URL: https://issues.apache.org/jira/browse/IGNITE-1694
> Project: Ignite
> Issue Type: Task
> Components: interop
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Fix For: 1.6
>
>
> Currently we invoke native platform using
> "Marshal.GetDelegateForFunctionPointer".
> This is the least efficient way to call external code. What can be done to
> improve it:
> 1) Add [SuppressUnmanagedCodeSecurity] attribute.
> 2) Use P/Invoke instead. We do not use it now because we unpack native
> library in runtime into some temp folder, while PInvoke searches for
> libraries in predefined file system places. Need to evaluate whether we can
> switch back to P/Invoke somehow.
> See
