Bug 578739 - Optimize ImageLoader copy to ByteArrayOutputStream Testing was done using three images. A simple screenshot (230kB), and two satellite image samples (15MB and 50MB) from https://effigis.com/en/solutions/satellite-images/satellite-image-samples/. Testing was conducted by timing in code how long the loop in the original code took, and then how long the transferTo() call took. By using transferTo(), instead of a loop the following speed improvements were seen: 1) On the 230kB file, loading was 20.7% faster 2) On the first 15MB Thailand satellite image, loading was 25% faster 3) On the 50MB Germany satellite image, loading was 22.7% faster Change-Id: I8042d7ded51444d4e6fffeca1ac2c5f6be5ad05a Signed-off-by: Joel Majano <jmajano@redhat.com> Reviewed-on: https://git.eclipse.org/r/c/platform/eclipse.platform.swt/+/190786 Tested-by: Alexander Kurtakov <akurtako@redhat.com> Reviewed-by: Alexander Kurtakov <akurtako@redhat.com>
