Hyperthreading hurts server performance, say developers
Talkback When hyperthreading first came out, I found a 2 proc hyperthread machine, (4 virtual), to spec close to 100% of a real 4 proc machine. The application used was a highly threaded isap ext, written in c++, running on IIS 5.0.

Hyperthreading hurts server performance, say developers
Talkback Hyperthreading causes unexpected table deadlocks and SQL rollbacks on IBM DB2 when running on Linux (tested on RHES 3 and 2.1). True dual processors do not cause the problem, only why hyperthreading is enabled.

Hyperthreading hurts server performance, say developers
Talkback We'll be turning off hyperthreading on our dual cpu servers. I believe the description of "trash" was accurate if one thread was clearing shared cache while another was using the cache.

Hyperthreading hurts server performance, say developers
Talkback We installed OOo in our Window XP workstations and we were having problems with soffice.bin allocating 100% of CPU usage since we disable the hyperthreading. This tecnology also hurts application performance such as OpenOffice.org suite.
