From 6dea5ec823c861de0a1490b2c6f9573e329e7e44 Mon Sep 17 00:00:00 2001 From: Matthias Sohn Date: Mon, 24 Oct 2016 13:26:58 +0200 Subject: [PATCH] Speedup CleanFilter by transferring data in chunks of 8k Transferring data byte per byte is slow, running add with CleanFilter on a 2.9MB file takes 20 seconds. Using a buffer of 8k shrinks this time to 70ms.
