Avenida (Performance Engineer)
Avenida solves performance problems in software systems, usually for the
largest companies in Denmark. This is done via standard and custom
performance monitoring platforms and performance analysis. Avenida is called
in IT emergencies, normally when all else fails. My role is split as a
performance engineer, doing time-critical analysis, and as a developer of the
performance monitoring platform.
Our projects are usually limited to 30-40 hours, so I worked on many projects
for a large shipping company and associated companies, government agencies,
a large clearing and security company, a large industrial engineering company,
hosting companies, a large law firm, some large retail companies, and many
midsize companies. The projects can be grouped as
 Weblogic, Oracle database, iAS in Java on Solaris and Linux – wrote a JMX Java
light weight sampling profiler

profiler for .NET, memory dumps
 VmWare ESX, Citrix XenApp & XenServer (EdgeSight), HyperV and Citrix client
profiles, Citrix over WAN lines
 Windows network checks for stack, teaming, cluster failover – wrote tool using
netsh, wmic, cscript, nvspbind, etc.

monitoring software in C# & PowerShell
 Optimization of BI systems like Hyperion and Qlikview
 Custom application analysis & optimization with architecture, configuration and
infrastructure. Role: technical advocate between customer and suppliers
 Analysis and optimization of software based on multiple technologies and
languages
 WAN analysis using wireshark, tshark, C# programs, etc.
 Optimization of Dynamics NAV & C5 (Navision & Concorde), IIS, Sql Server, SAN
 Dynamics AX (Axapta) integration optimization at AOS and Sql Server level plus
clustered SqlServer setup up to AX 2012 R3
