The on-demand scanner (ODS), introduced in VSE 8.8 Patch 3, underwent some reconstruction in how it manages scan threads. The change was an effort to resolve a reported symptom of high memory use from the Scan32 or Scan64 process. Memory use was reported in the gigabyte ranges, which was very high. The solution implemented was to reduce the number of available scan threads. The result was that the ODS took longer to complete the same scan tasks. This deterioration of performance continues to exist in VSE 8.8 Patch 4.
