> Key: IGNITE-1785
> URL: https://issues.apache.org/jira/browse/IGNITE-1785
> Project: Ignite
> Issue Type: Improvement
> Components: interop
> Affects Versions: 1.5
> Reporter: Pavel Tupitsyn
>
> * PlatformMemory is just a single "long _memPtr" and can be easily converted to a struct to reduce allocations (it is allocated a lot)
> * PlatformMemoryStream works with PlatformMemory.Length and Capacity indirectly. By employing a struct approach from https://issues.apache.org/jira/browse/IGNITE-1428 we can work with Length and Capacity directly, which may be faster, and will eliminate the need for SyncronizeInput/Output calls.
> * PlatformMemoryStream is allocated even more often than PlatformMemory, need to investigate whether it can also be a struct. See how List<>.GetEnumerator works, which is a struct.
