[Moosefs-users] about mfs_mount client performance

[丁赞 <di...@ba...>]

Hi all

 

       FUSE is a accept+fock module, which means if N clients(500+ httpd
threads in our enviroment) read data from mfs through one mfs_mount
simultaneously, FUSE could create N threads to handle the requests. This
mechanism spent much more  time on context siwtch，which made apache
response time much more longer in our enviroment。SO anyone had tried to
promote the fuse or mfs_client performace? Using threads pool or user level
cache would work???

 

 

BTW：I am a new guy here：）

 

Thanks all

Hi!

 

We think that the best solution would be creating a dedicated module in HTTPD for MooseFS. But as we think about it we cannot tell when we could prepare it.

 

If you need any further assistance please let us know.

 

 

Kind regards
