Re: [Gluster-devel] gluster 3.0.0 catastrophic crash during basic file creation test

Hi Gordan,

Thanks for your feedback on unfsd. We will have a look.

How's the experience on 3.0.2rc1, performance wise, between a Gluster client 
and server using the native protocol ? Did you see that worsen in comparison to 
2.0.9 or improve compared to 2.0.9 ? Would be very interested to know.

Regards,
Tejas.

I'm no longer that convinced. My observation is that latencies in the 
glfs+unfsd use-case are _much_ higher with 3.0.2rc1 than they were with 
2.0.9. So much higher that the setup is nearly unusable for /home. I 
haven't observed this slow-down with other things on glfs root, though, 
only with unfsd exports. io-cache and write-behind translators seem to 
help a lot, but I'm still weary of using any performance translators at 
the moment, especially with the spurious disconnects I mentioned in a 
separate thread.
