I had the intention of using GlusterFS to replace DRBD to setup a clustered/redundant webserver but so far the performance is about 7-8x slower than native due to the live writing feature that GlusterFS uses. Is it possible to have a setup like DRBD to improve performance? Basically I want to know if I can get the same functionality and performance of DRBD? I have 2 servers and with DRBD each server would perform all reads locally (giving native performance) and does not write data until it is fully written locally (delayed write I guess you could say). This way you get the replication but still get native performance. Is there a current way to setup GlusterFS like this in order to get this 'DRBD-like' functionality?
