As written in in http://plan9.bell-labs.com/sys/doc/venti/venti.html - "The prototype Venti server is implemented for the Plan 9 operating system in about 10,000 lines of C. The server runs on a dedicated dual 550Mhz Pentium III processor system with 2 Gbyte of memory and is accessed over a 100Mbs Ethernet network. The data log is stored on a 500 Gbyte MaxTronic IDE Raid 5 Array and the index resides on a string of 8 Seagate Cheetah 18XL 9 Gbyte SCSI drives." God ide is to store isect on multiple SSD drives :) to speed up search. My small installation - 80Gb (PATA) 9fat, fossil, swap + 40Gb isect, bloom drive (PATA) + 1Tb SATA as arenas. No RAID. 2015-05-04 21:51 GMT+03:00 David du Colombier <0intro@gmail.com>: > I'm experiencing the same issue as well. > > When I launch vacfs on the same machine as Venti, > reading is very slow.

I'm experiencing the same issue as well.

When I launch vacfs on the same machine as Venti,
reading is very slow. When I launch vacfs on another
Plan 9 or Unix machine, reading is fast.

I've just made some measurements when reading a file:

Vacfs running on the same machine as Venti: 151 KB/s
Vacfs running on another machine: 5131 KB/s
