Reconsider sizes of file read/write buffers

Currently we use 32 kB buffers to read and write files in Firefox. Given typical file sizes of 2-3 MB this might result in too many I/O operations and suboptimal performance.

What to change

Find out how large the buffer can be to avoid increasing startup delays significantly, freezing UI when filters are changed or overusing memory.

  • Resolution set to rejected
  • Status changed from new to closed

Mass-closing all bugs in Adblock Plus for Firefox module, the codebase of Adblock Plus 3.0 belongs into Platform and User-Interface modules. Old bugs are unlikely to still apply.
