[ZODB-Dev] Statistics on Blob-support for ZEO

[Christian Theune]

Hi,

ZEO now also supports BLOBs. Yeah.

Here the statistic for the sweet-spot file residing in OFS.File and
OFS.Blob.File in a ZEO setup: 

OFS.File.File
-------------
Document Length:        4964315 bytes

Concurrency Level:      20
Time taken for tests:   321.600003 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      698404551 bytes
HTML transferred:       698133763 bytes
Requests per second:    3.11 [#/sec] (mean)
Time per request:       6432.000 [ms] (mean)
Time per request:       321.600 [ms] (mean, across all concurrent
requests)
Transfer rate:          2120.76 [Kbytes/sec] received

The Zope server was pretty unresponsive during this test.

OFS.Blob.File
-------------

Document Length:        4964315 bytes

Concurrency Level:      20
Time taken for tests:   60.233328 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      703069088 bytes
HTML transferred:       702902136 bytes
Requests per second:    16.60 [#/sec] (mean)
Time per request:       1204.667 [ms] (mean)
Time per request:       60.233 [ms] (mean, across all concurrent
requests)
Transfer rate:          11398.84 [Kbytes/sec] received

During this test, the Zope server was noticably slower than without
load, but still pretty responsive.

Hope you enjoy that.

Christian
