Thank you in advance. The configuration is not really optimal. I would advise you to: - remove io-threads (io-threads is only really needed on the server). - remove read-ahead, it won't help in this case. - increase the cache-timeout to a higher value for quick-read, since you are doing only reads. Please tell us the numbers you get after making these changes. You should also do atleast a few thousand requests to smooth out random fluctuations. Comparing the times for a single request does not tell us much. ------------------------------ Vikas Gorur Engineer - Gluster, Inc. ------------------------------
