 The hardware requirements for Omnidex applications vary depending on the size of the database, the nature of the queries and the number of users. ​ That being said, most Omnidex servers are commodity servers with plenty of memory and fast disk access. ​ There are typically two hardware profiles: The hardware requirements for Omnidex applications vary depending on the size of the database, the nature of the queries and the number of users. ​ That being said, most Omnidex servers are commodity servers with plenty of memory and fast disk access. ​ There are typically two hardware profiles:

 An Omnidex Indexing Server is used to load the indexes on large databases. ​ Companies often receive new data on a regular basis, and since most Omnidex databases have a great deal of indexing, it is better to rebuild some or all of the indexes, rather than applying the updates one at a time.  Applications that can be taken offline while indexing occurs do no need a separate Omnidex Indexing Server, but when an application must remain available all of the time, indexing usually occurs on a separate server. ​ An Omnidex Indexing Server is used to load the indexes on large databases. ​ Companies often receive new data on a regular basis, and since most Omnidex databases have a great deal of indexing, it is better to rebuild some or all of the indexes, rather than applying the updates one at a time.  Applications that can be taken offline while indexing occurs do no need a separate Omnidex Indexing Server, but when an application must remain available all of the time, indexing usually occurs on a separate server. ​

 Omnidex Query Servers benefit from multi-processor machines so that queries can be processed in parallel. ​ It is also valuable to avoid other large processing tasks on an Omnidex Query Server. ​ An important key to Omnidex performance is to complete queries quickly before the operating system swaps that process out to process another task.  ​ Omnidex Query Servers benefit from multi-processor machines so that queries can be processed in parallel. ​ It is also valuable to avoid other large processing tasks on an Omnidex Query Server. ​ An important key to Omnidex performance is to complete queries quickly before the operating system swaps that process out to process another task.  ​

-===== Windows or Linux? ​=====+===== Operating System Recommendations ​=====
  
 We are often asked which is faster, Linux or Windows? ​ It is not an easy question to answer. ​ There are so many other variables, such as the database platform, the amount of memory, the approach to disk storage, and so forth. ​ In a company, the hardware acquisition and personnel costs can be large enough to outweigh the benefit of a slightly faster hardware platform. ​ Because of this, we recommend that each company test with their own hardware, their own database platform and their own client layers. We are often asked which is faster, Linux or Windows? ​ It is not an easy question to answer. ​ There are so many other variables, such as the database platform, the amount of memory, the approach to disk storage, and so forth. ​ In a company, the hardware acquisition and personnel costs can be large enough to outweigh the benefit of a slightly faster hardware platform. ​ Because of this, we recommend that each company test with their own hardware, their own database platform and their own client layers.
