Subject: latancy test of -ac22-riel
Date: Tue, 20 Jun 2000 08:13:00 +0200	[thread overview]
Message-ID: <394F0B6C.3925591B@norran.net> (raw)

Hi all,

Things are looking better and better :-)
Running with SCHED_FIFO now gives most interrupt to process
latencies below 3 ms !!!
(streaming 1.5 times RAM; read, write, copy tested)

But there are some, nowadays very few, spikes that hurts...
Worst is above 100 ms

But in this kernel does not have the loop limits in shrink_mmap

/RogerL

PS
  Used test programs are at:
  http://www.gardena.net/benno/linux/audio 
  for test programs.
